One of the most prolific men in music, Bill Laswell doesn't release albums under his own name as often as he once did, which makes Book of Exit, the fourth in his "Dub Chamber" series, especially worthy of attention. While the previous "Dub Chamber" releases leaned more toward hard Jamaican-style dub music, with instruments dropping in and out and plenty of reverb and delay, this is altogether a different beat, in large part due to the vocals of Ethiopian singer Gigi. And what Laswell, Gigi, drummer/tabla player Karsh Kale, and percussionist Aiyb Dieng end up with is really ambient dub - something lighter and more flowing because it adapts itself to the vocals. And Gigi is in excellent form, possibly better than on her own debut, whether on "Ethiopia" or the memorable, beautiful "Jerusalem," which mixes a slight R&B inflection with dub for something outstanding, beautiful, and ethereal…

Barbara McNair is certainly not the only singer to get lost in the shuffle at Motown at the company's mid-'60s zenith, but her tenure there seemed particularly star-crossed – as this 48-track Ultimate Motown Collection illustrates, much of her finest material was inexplicably withheld from release (in particular the much-bootlegged Northern soul classic "Baby a Go-Go"), while official singles like "My World Is Empty Without You" were issued in the wake of existing hit renditions by other Motown artists. But McNair boasted a genuinely sophisticated, sexy style that was unique in the Motown canon, and her voice – though by no means a powerhouse – is nevertheless stronger and more affecting than Diana Ross, whose hand-me-downs she often received. Compiling her full-lengths Here I Am and The Real Barbara McNair, the unreleased Barbara McNair Sings Smokey, non-LP singles, and rare vault material, this two-disc set finally pays McNair the respect she's always deserved – complete with informative liner notes and excellent sound, it's tough to imagine a better representation of her music.

The late singer and songwriter Blaze Foley is almost unheard of outside of the circles of music fans who follow that scene closely. For many Austin musicians, he was a crazy saint, an iconoclast who was banned from virtually every bar in town, but whose songs are deeply admired and whose persona was singular – he didn't give a good god damn what anybody thought of him. He has been immortalized in Lucinda Williams' beautiful "Drunken Angel" and songwriter-guitarist Gurf Morlix, who played with him, lovingly mastered a record they made together in the late '70s which was released in 2006 as Blaze Foley & the Beaver Valley Boys. Willie Nelson, Merle Haggard, Kings of Leon, Lyle Lovett, and John Prine, among others, have recorded his songs. He's been exploited on a few compilations that have come out over the years with awful post-production work that he would never have agreed to. Fat Possum deepens the legend further without soiling the artist in the process. The Dawg Years is a collection of 20 Foley songs, recorded when his moniker was Deputy Dawg.

Best Of…, also referred to as Sia: Best Of…, is the first greatest hits album by Australian singer-songwriter Sia, released in Australia on 30 March 2012 through the Sydney-based independent record label Inertia.[2] The compilation includes tracks from four of her previous studio albums: Healing Is Difficult (2001), Colour the Small One (2004), Some People Have Real Problems, (2008) and We Are Born (2010). Also included are two tracks featuring Sia as a vocalist ("Destiny" by Zero 7 and "Titanium" by David Guetta), "My Love" from The Twilight Saga: Eclipse film soundtrack, plus a remixed version of "Buttons" by Brazilian rock band CSS.

In nearly all his pieces, Duphly presents two contrasting images—the bold and brazen virtuoso, and the wistful dreamer. The one exploits the compass of the harpsichord with scales and dense chords while the other enchants with delicately voiced textures. Only occasionally, as in pieces such as the fiercely passionate ''Medee'', or the elegant ''Les Graces'', does one mood prevail. Nimbly shifting back and forth between these extremes within pieces (as, for example in ''La larare'' or ''La d'Hericourt'') and between them presents a formidable challenge to any performer.

The Art of Renée Fleming is essentially an album of the soprano's most popular hits, probably not targeted at listeners who are already big fans (who are likely to already have the albums from which these selections were culled), but at more general audiences interested in expanding their operatic horizons. With a few very familiar exceptions, the songs and arias are from the Romantic and post-Romantic eras, and showcase the luxurious creaminess of Fleming's voice and her ability to spin out melodic lines with seamless, soaring lyricism.

An invitation to experience music played in the court of Versailles – for Louis XIV and his successors. An imaginary story gives it its framework: A young provincial beauty comes to the court, is presented to the King and becomes his favourite, falls into disgrace through the intrigues of her rivals, but finally retrieves her honour.

When one speaks of a man full of fire, genius and life, one has to think of Monsieur Guillemain, Musician to the King; he is perhaps the most extraordinary and adroit violinist one can hear play. There are no difficulties that can stump him and he can compose learned pieces which sometimes embarrass his rivals. Among the great Masters, this celebrated artist is one of the most productive. His works are full of touching beauty.

Since Bonnie Raitt didn't score any big hits during her nine-album tenure at Warner Bros., compiling a best-of from those records is largely a matter of taste, and after Raitt's commercial breakthrough on Capitol with Nick of Time in 1989, Warners decided to trust her own taste in choosing songs for this compilation. The artist's input is usually considered a good thing, but in this case it has resulted in an idiosyncratic selection that fails to be representative or to cull the real highlights from Raitt's Warners catalog. Basically, that catalog breaks down into three sections - the first three solid albums, the second three good but uneven albums, and the last three mediocre, compromised albums. Raitt has opted to try to find at least a couple of tracks from each album, which means she necessarily slights her best work in favor of her weakest…

Heron's self-titled debut LP was mild, drummerless British folk-rock with the rural/pastoral feel common to many early-'70s records in the style. That pastoral feel, in this particular case, might have been in part deliberate; the record was actually recorded in a field by the River Thames, and though the sound quality is very good, you can occasionally hear some birds and faint ambient outdoor noises. The music is very friendly, acoustic guitar-based stuff that, as improbable as such a blend may seem, is a little like a combination of Simon & Garfunkel with the Incredible String Band, though there aren't many of the weirder elements of the latter. You might also cite the most acoustic and folky Paul McCartney ballads of the late '60s and early '70s (à la "Blackbird") and the harmonies of Crosby, Stills and Nash as less prominent influences. Some organ, piano, and accordion add a little depth to what's essentially an acoustic folk base.

For connoisseurs of modern jazz guitar, “Conversation” will be a revelation. The interplay between the two guitarists Pat Martino and Michael Sagmeister is marked by profound mutual understanding - which is no small wonder, considering Michael Sagmeister has long been interested in Martino’s music. In the meantime, these two world-class musicians are connected by a personal friendship, and they now communicate as two equals. Joining them are Michael Sagmeister’s long-standing rhythm group, Michael Küttner on drums, Thomas Heidepriem on bass. The powerful and flowing grooves of the two musicians form the basis for the unfolding of well-set lines and improvisations by Martino and Sagmeister. The tradition of modern jazz guitar can be followed in exemplary form on “Conversation”, and at the same time, one can hear how a guitar duo should sound in our time.

This fabulous five disc set is replete with some of those old Stokowski warhorses all recorded in absolutely mind boggling Phase 4 sound, overblown perhaps but astounding for its time. Decca's remastering is absolutely magnificent and the discs are jam packed with almost six hours of music. This is another fine memorial to a great conductor who remained astonishingly vital until the very end of his life.
