Skunk Work

The Jon Spencer Blues Explosion were one of the most viscerally exciting indie rock acts of the 1990s, but making their blast of frantic energy work in the studio was sometimes a challenge if you were going for anything more than sheer gutbucket stomp. On Orange and Acme, JSBX used strings, hip-hop beats, and various production niceties to add texture to the two-guitar-and-drums onslaught, but with Now I Got Worry, they moved forward into the past with the fiercest and most elemental set they'd released since Crypt Style. Now I Got Worry kicks off with Spencer screaming his head off while Russell Simins lays down a funky, muscular backbeat, and that sets the tone for what follows; the album plays at full-blast from beginning to end, even when the tempo shifts and the band eases back a bit in the name of dynamics.

MC5 were nearing the end of their long and bumpy trail when they cut High Time in 1971, and it was widely ignored upon initial release. While it lacks the flame-thrower energy and "off the man!" politics of Kick Out the Jams or the frantic pace and "AM Radio of the People" sound of Back in the USA, High Time sounds like MC5's relative equivalent to the Velvet Underground's Loaded, their last and most accessible album, but still highly idiosyncratic and full of well-written, solidly played tunes. Fred Smith's "Sister Anne" and "Skunk (Sonically Speaking)" bookend the album with a pair of smart, solidly performed hard rockers (bolstered by fine horn charts), and Wayne Kramer's "Poison" ranks with the best songs he brought to the band (he later revived it for his solo album The Hard Stuff)…

German-born composer and arranger Claus Ogerman, born in 1930, must rank as one of the most versatile musicians of the twentieth century. When he was at his peak in the 1970s, writing everything from ballet scores to arrangements for Brazilian composer Antonio Carlos Jobim, diva Barbra Streisand, and jazz/R&B saxophonist George Benson, there was hardly a radio station on the dial where his music wasn't heard during the course of a typical day – and he's still quite active. The key to his success has been his ability to stay in the background behind the musician he's working with and yet create something distinctive. This 1982 collaboration with the late jazz saxophonist Michael Brecker is one of his most successful works, not least because the overlap between the extended harmonies of jazz and the chromaticism of the late German Romantic polyphony in which Ogerman was trained is large enough to allow Brecker to operate comfortably – his improvisations seem to grow naturally out of the background, and the intersections between jazz band and orchestral strings come more easily here than on almost any other crossover between jazz and classical music.

Walter Becker and Donald Fagen were remarkable craftsmen from the start, as Steely Dan's debut, Can't Buy a Thrill, illustrates. Each song is tightly constructed, with interlocking chords and gracefully interwoven melodies, buoyed by clever, cryptic lyrics. All of these are hallmarks of Steely Dan's signature sound, but what is most remarkable about the record is the way it differs from their later albums. Of course, one of the most notable differences is the presence of vocalist David Palmer, a professional blue-eyed soul vocalist who oversings the handful of tracks where he takes the lead. Palmer's very presence signals the one major flaw with the album – in an attempt to appeal to a wide audience, Becker and Fagen tempered their wildest impulses with mainstream pop techniques.

Gary Moore - one of rock's most underrated guitarists (both from a technical and compositional point of view), Gary Moore remains relatively unknown in the U.S., while his solo work has brought him substantial acclaim and commercial success in most other parts of the world – especially in Europe. Born on April 4, 1952, in Belfast, Ireland, Moore became interested in guitar during the '60s, upon discovering such blues-rock masters as Eric Clapton, Jimi Hendrix, and perhaps his biggest influence of all, Fleetwood Mac's Peter Green.
