A complete survey of Ravel’s piano music is an especially challenging prospect for any pianist. It is not merely that this sublime music frequently demands exceptional, post-Lisztian virtuosity. Beyond such dexterity is the fact that, as Steven Osborne observes in this recording’s booklet, the composer’s fear of repeating himself ensure that the lessons from one work can rarely be transferred to the next. This is not merely the aesthetic change from the nightmarish imagery of Gaspard de la nuit to the elegant neo-classicism of Le tombeau de Couperin. Ravel essentially re-imagined how to write for the piano with each significant work. Osborne is more than up to the task. The contrasting fireworks of the ‘Toccata’ from Le tombeau and ‘Alborada del gracioso’ (Miroirs) are despatched with relish, the piano exploding with power in the latter after a disarmingly impish opening. The Sonatine has a refined insouciance, while the love bestowed upon each note is clear. Then there are the numerous moments of sustained control, such as the shimmering opening pages of Gaspard. Sometimes changes of spirit occur effortlessly within a piece. Having been a model of clarity in the ‘Prelude’ from Le tombeau, Osborne treats the codetta not as a brisk flourish, but as if this particular vision of the 18th century is dissolving beneath his fingers.

Although this is billed to Wes Montgomery, it is in fact a combination of two early-'60s LPs by the Montgomery Brothers – The Montgomery Brothers and The Montgomery Brothers in Canada – onto one disc. (Also note that it's almost entirely different from the Montgomery Brothers' Milestone double LP that also bears the name Groove Brothers, which mostly features material from their Riverside LP Groove Yard.) With Wes on guitar, Monk on bass, and Buddy on piano (Larance Marable fills out the quartet on drums), The Montgomery Brothers (1960) is a boppish set of five lengthy tracks, divided between both originals (penned by either Wes or Buddy) and standards. "June in January" is a particularly good vehicle for Wes' fluid single-note runs, while "D-Natural Blues" is one of his more enduring and good-natured compositions from the period. Buddy Montgomery, who often played the piano with the Montgomery Brothers, sticks exclusively to vibes on The Montgomery Brothers in Canada, which in addition to Wes and Monk has Paul Humphrey on drums.

"La Gloria, Roma e Valore" by Giovanni Lorenzo Lulier (1662 -1700) is a solemn cantata for the inauguration of the new Venetian ambassador in Rome. Whoever thought that this is only ephemeral baroque music, is wrong: Often the composers showed what they were able to do, because unlike for example in the Opera House, in the audience were musical experts and potential constituents. The protégé of Cardinal Pietro Ottoboni has really created a small musical jewel, which was convincingly recorded by Fabio Missaggia and I Musicali Affetti.

Another installment in Collectables' The Ultimate Christmas Album series, volume four gathers a mix of well-known and offbeat holiday tunes, including Elvis Presley's "Blue Christmas," the Platters' "Winter Wonderland," and Perry Como's "It's Beginning to Look a Lot Like Christmas." Brook Benton's "You're All I Want for Christmas," Percy Faith's "Christmas Is," and Otis Redding's "Merry Christmas Baby" are some of the collection's soulful highlights, while Santo & Johnny's "Twistin' Bells" and Stan Freberg's "Christmas Dragnet" add some novelty to the festivities. Though it's a somewhat uneven collection, The Ultimate Christmas Album, Vol. 4: WCBS 101.1 has enough interesting and classic moments to make it worthwhile for anyone looking to go beyond the season's basic music.

Released a year after Eat a Peach, Brothers and Sisters shows off a leaner brand of musicianship, which, coupled with a pair of serious crowd-pleasers, "Ramblin' Man" and "Jessica," helped drive it to the top of the charts for a month and a half and to platinum record sales. This was the first album to feature the group's new lineup, with Chuck Leavell on keyboards and Lamar Williams on bass, as well as Dickey Betts' emergence as a singer alongside Gregg Allman. The tracks appear on the album in the order in which they were recorded, and the first three, up through "Ramblin' Man," feature Berry Oakley - their sound is rock-hard and crisp. The subsequent songs with Williams have the bass buried in the mix, and an overall muddier sound…

That it took nearly a year to record Voulez-Vous is an indicator of the creative and personal constraints in which the four members of ABBA found themselves at the end of the '70s. Their sixth album coincided with the marital split between Agnetha Fältskog and Björn Ulvaeus and the massively shifting currents in popular music, with disco, which had been on the wane, suddenly undergoing a renaissance thanks to the 1977 movie Saturday Night Fever. Thus, about half of Voulez-Vous shows the heavy influence of the Bee Gees from their megahit disco era. This is shown not just in the fact that the backing track for the title song was cut at Criteria Studios in Miami, where the Bee Gees had cut Main Course, Children of the World, and most of the rest of their disco-era music, but through the funky beat that ran through much of the material…

The sixth album by New York's Holmes Brothers is another all-spirituals set - though not in the traditional sense of the word. Produced by pop singer Joan Osborne (before she was a superstar, Osborne woodshedded with the Brothers and developed a fine rootsy singing style of her own), who was there in the Manhattan trenches with the band, this set goes a long, long way to capturing raw, excruciating grooves. With the a trio of singers as soulful as any group Memphis or Motown ever produced, the Holmes Brothers take it to the gut each and every time. This set opens with Ben Harper's "Homeless Child," and let's just say after the deep, grease-fire funk the vocalizing creates, Harper should never play it again. This song now belongs to the Holmes Brothers…
