Legendary English rock band, Humble Pie may be best known in the U.S. for their minor hit songs "30 Days In The Hole" and "I Don't Need No Doctor." They jumped onto the music scene in 1969 with their U.K. hit single "Natural Born Bugie," before turning their attention to a more bluesier sound. In 1974, following the success of their album "Thunderbird," Humble Pie entered their own home-built studio to record a follow-up album of cover songs mixed with originals. The result was "Joint Effort," but the album was eventually shelved by the band's record label. Now, 45 years later, Humble Pie's "Joint Effort" will be released for the first time on CD and on vinyl.
