Some bands just keep on truckin'. Check out Canned Heat, closing out the millennium with a new album of new material. This is a good title for the album because since forming 33 years ago, the band is still going on fusing boogie rhythms with rock instrumentation. Still, there is plenty of variety here. On "World of Make Believe" they go halfway to meeting Santana and on "Dark Clouds" they recall Willie Dixon.

Canned Heat's second long-player, Boogie with Canned Heat (1968), pretty well sums up the bona fide blend of amplified late-'60s electric rhythm and blues, with an expressed emphasis on loose and limber boogie-woogie. The quintet – consisting of Alan "Blind Owl" Wilson (guitar/harmonica/vocals), Larry "The Mole" Taylor (bass), Henry "Sunflower" Vestine (guitar), Aldolfo "Fido" Dela Parra (drums), and Bob "The Bear" Hite (vocals) – follow up their debut effort with another batch of authentic interpretations, augmented by their own exceptional instrumentation. One development is their incorporation of strong original compositions. "On the Road Again" – which became the combo's first, and arguably, most significant hit – as well as the Albert King inspired anti-speed anthem, "Amphetamine Annie," were not only programmed on the then-burgeoning underground FM radio waves, but also on the more adventuresome AM Top 40 stations. Their love of authentic R&B informs "World in a Jug," the dark "Turpentine Blues," and Hite's update of Tommy McClennan's "Whiskey Headed Woman".

Canned Heat 1967-1976: The Boogie House Tapes is a double-disc set, assembled by drummer Adolfo de la Parra, the only remaining member of the original '60s band, and Canned Heat collector Walter de Paduwa; it's a compilation of some previously "lost" studio and live performances of the indefatigable boogie band. While hardcore fans will rejoice hearing the great Alan Wilson, who appears on roughly half of these tracks, in his prime, it's still a very mixed bag. Guitarists Harvey Mandel and Henry Vestine are featured prominently, as is vocalist Bob "the Bear" Hite who, along with drummer de la Parra, is the only constant band member across these two CDs.

These are the earliest-known recordings of Canned Heat with the primordial lineup of Alan "Blind Owl" Wilson (guitar/harmonica/vocals), Stuart Brotman (bass), Henry "Sunflower" Vestine (guitar), Bob "The Bear" Hite (vocals), and either Keith Sawyer (drums), or perhaps his replacement, Frank Cook (drums), who joined circa 1966. Another notable name among the personnel listed on the original LP jacket is rhythm & blues legend, Johnny Otis as producer. This is certainly fitting, as the Heat wind their way through compact, high-energy versions of a variety of selections, directly contrasting the longer psychedelic showcases that would evolve over the next few years.

Canned Heat founder and guitar great Bob Hite once described his band as "a rock band with country/blues roots" and perhaps a little less modestly, "the first and greatest boogie band ever." Canned Heat's "greatness" has always seemed to elude them by a hair, however, regardless of their versatility and devotion to the strange and wonderful mutations their music endured, particularly in the '60s. But these dudes do nothing if not persevere. Having lost their signature falsetto and lowdown harp man Alan Wilson in 1970, 1996's Canned Heat Blues Band fronts "The Bear's" third vocal replacement, Robert Lucas, who wisely doesn't pretend he can cover those cool old road-trip-on-acid songs (like "Going Up the Country") in a particularly familiar manner.

When this two-LP set was initially released in January 1971, Canned Heat was back to its R&B roots, sporting slightly revised personnel. In the spring of the previous year, Larry "The Mole" Taylor (bass) and Harvey Mandel (guitar) simultaneously accepted invitations to join John Mayall's concurrent incarnation of the Bluesbreakers…

Canned Heat are celebrating in 2015 their 50th birthday. Since 1967 Adolfo Fito de la Parra is the drummer and Larry The Mole Taylor on bass and guitar was in periods always in the line-up. Together they are the force and musicians who keep The Heat alive; on tour and by recordings…
