Thanks to the 1970s and '80s soul jazz movement and its 21st century counterpart, acid jazz, the Hammond B-3 organ has shown a remarkable ability to survive and adapt to changing musical trends – all without changing its swirling, pulsing tone one little bit. The Hammond Street anthology from Acid Jazz mixes in tracks from a couple of veteran B-3 players like Jimmy McGriff and Reuben Wilson with tracks from newer combos, and even though these newer groups cover songs like Nirvana's "Smells Like Teen Spirit," what is immediately obvious here is how much a B-3 sounds like a B-3 no matter what kind of clothes you drape over it. Highlights include the hard-charging "Itchy Feet" by the Past Present Organisation (which opens the disc), the ragged and energy-overloaded "Clubtown" by the Trashmonkeys, McGriff's "Ain't It Funky" (which indeed it is), and Wilson's "Sugar," a classic piece of soul jazz.

The best of all of Al Kooper's studio albums, Rekooperation is a mostly instrumental album, on which the artist (playing organ and piano, and occasional guitar) and a band including Jimmy Vivino, Harvey Brooks, and Fred Walcott, among others, roar and pound their way through a baker's dozen of R&B, rock & roll, and soul classics. Everything from chestnuts like "Soul Twist," "Honky Tonk," "Johnny B. Goode," "Clean Up Woman," and " "Don't Be Cruel" to originals such as "Downtime" and "Alvino Johnson's Shuffle," without a notable gap in quality between them, are included – and the one vocal number, "I Wanna Little Girl," contains one of the finest singing performances that Kooper has ever turned in on record (but is also played so well, that it would work as an instrumental too). In many ways, this recording is a distant cousin to Blood, Sweat & Tears' Child Is Father to the Man, and was his first attempt at leading a band since that 1968 venture, which was sort of fitting since it led to Soul of a Man, Kooper's live-in-concert career retrospective album, the next time out.
