He recorded his second solo album, "Try It Before You Buy It", in 1973. Columbia rejected it; the complete version of the record would not appear until 1990. Also in 1973, he cut "Triumvirate" with Dr. John and guitarist and singer John Hammond Jr. In 1974, he rejoined the Electric Flag for an album titled "The Band Kept Playing". In 1975 he recorded an album with the group KGB. The group's name is an acronym of the initials of singer and songwriter Ray Kennedy, Barry Goldberg and Bloomfield. The band also included Ric Grech and drummer Carmine Appice. Grech and Bloomfield quit shortly after its release. As the record hit stores in 1976, Bloomfield told journalists that the group had been an ill-conceived moneymaking project. The album was not well received by critics, but it did contain the standout track "Sail On, Sailor". Its authorship was credited to "Wilson-Kennedy", and had a bluesy, darker feel, along with Ray Kennedy's original cocaine-related lyrics. In the same year, he performed with John Cale on Cale's soundtrack for the film "Caged Heat". In 1976 he recorded an instructional album for guitarists, "If You Love These Blues, Play 'Em as You Please", which was financed through "Guitar Player" magazine.
