Future Blues is the fifth album by American rock band Canned Heat, released in 1970. It was the last to feature the band's classic lineup, as Larry Taylor and Harvey Mandel had both departed by July 1970, prior to its release to record with John Mayall and songwriter Alan Wilson died shortly after on September 3, 1970. It was also the only classic-era Canned Heat studio album to feature Mandel, as Henry Vestine had been the lead guitarist on the previous albums. Their cover of "Let's Work Together" by Wilbert Harrison became a hit. "London Blues" features Dr. John. It was re-released on CD in 2002 by MAM productions with five bonus tracks.
