Loose and spontaneous, this (mainly) live album is a meeting of three of the greatest guitarists in the world for an acoustic summit the likes of which the guitar-playing community rarely sees. Broken up into three duo and two trio performances, Friday Night in San Francisco catches all three players at the peaks of their quite formidable powers.

In the wake of Madonna's success, many dance-pop divas filled the charts, but out of them all, Paula Abdul was the only one who sustained a career. The former L.A. Lakers cheerleader and choreographer scored her first hit in 1989, when "Straight Up" shot to Billboard's number one spot, becoming the first of four U.S. chart-toppers from her 1988 debut, Forever Your Girl; the others were "Forever Your Girl," "Cold Hearted," and "Opposites Attract," each earning a gold certification from the RIAA. This success laid the groundwork for her second act as a judge on American Idol, the televised singing competition that began in 2002 and kept Abdul in the spotlight throughout the decade.

Rameau on the piano? It's not altogether unheard of – there were a handful of classic recordings made by Robert Casadesus back in 1952 – but, despite many recordings of Bach, Handel, and Scarlatti on the piano in the digital age, there's been precious little Rameau on the piano until this Angela Hewitt recording of three complete suites from 2006. By choosing the Suite in E minor from the Pièces de clavecin of 1731 plus the Suites in G minor and A minor from Nouvelles suites de pièces de clavecin, Hewitt has for the most part stayed away from the more evocatively titled works and stuck to the standard stylized Baroque dance forms of the allemande, courante, and gigue. Justly celebrated for her cool and clean Bach recordings, this strategy works well for Hewitt. Without seeming to resort to the sustain or the mute pedal, she floats Rameau's lines and melodies, and without seeming to exaggerate the accents or dynamics, she gives Rameau's rhythms a wonderful sense of lift. In the deliberately evocative movements from the G minor Suite – "La poule," "Les sauvages," and especially "L'egiptienne" – Hewitt seems to bring less to the music – her interpretations are remarkably straight – and to get less out of it – her performances are remarkably bland.

One of his finest '90s recordings, Chill Out balances the guitar-glitz of Carlos Santana's guest shot on the karmic title cut with a handful of profoundly deep Hooker solo performances. Among those are new versions of his standards "Tupelo" and "Annie Mae," and the soulful "If You've Never Been in Love," where expert slide-man Roy Rogers provides subtle accompaniment to Hooker's spontaneous storytelling. The band numbers that bookend the album are weak, relying on Hooker's strong vocal presence to overcome sketchy writing. Van Morrison, pianist Charles Brown, and M.G.'s leader Booker T. Jones also lend a hand. But Hooker doesn't need anybody's help to get to the passionate heart of his blues. One last note: Anton Corbijn's CD-booklet photographs of ol' Johnny Lee are terrific.

Originally released in 1975, follow up to Snowflakes are Dancing. Versions of Mussorgsky's Pictures at an Exhibition. Carefully and painstakingly constructed with a bigger sound than before. Comes with bonus track of Rimsky-Korsakov's Scheherazade and J.S. Bach's The Sea Named Solaris.

Manhole was the last of the experimental Jefferson Airplane, and Grace Slick's first official solo album. While Bark and Long John Silver, the final stages of the original Airplane, displayed the excessive psychedelic nature of the musicians within the confines of their group format, Blows Against the Empire, Sunfighter, and Baron Von Tollbooth and the Chrome Nun allowed for total artistic expression. Manhole concluded this phase with 1974's other release, the Jefferson Starship's Dragonfly. By taking the name from Paul Kantner's Blows Against the Empire solo project, Dragonfly began the renewed focus on commercial FM which would turn into Top 40 airplay. Manhole is the antithesis of that aim, but is itself a striking picture of Grace Slick as the debutante turned hippy being as musically radical as possible…

The final volume in this very worthy series is a comparatively relaxed affair, a quartet set with tenor saxophonist Ben Webster. Webster lets Tatum fill the background with an infinite number of notes while emphasizing his warm tenor in the forefront on a variety of melodic ballads and standards. The combination works very well.

The Mars Volta's 2003 debut was a dense, experimental run-on sentence of science fiction and musical exploration. But though it ultimately rewarded patience with stretches of unbuckled rock & roll genius, De-Loused in the Comatorium was also a maze-like and obtuse migraine dealer that made people frustrated and crazy. For 2005's Frances the Mute, Omar Rodriguez-Lopez and Cedric Bixler-Zavala worked principally with their touring band, but "joining the band for selected moments" are strings, horns, electronic programming, pals Flea and John Frusciante, and the coqui frogs of Puerto Rico. There are no song breaks, making the track listing more of an outline. But Mute's printed lyrics are a helpful guide, a map of Mars that's meant to both direct and fascinate…
