The Aerovons
The Aerovons were an American rock band from St Louis, Missouri formed in 1966. History
They were formed in 1966 in St Louis, Missouri by Tom Hartman. A 1967 demo record was heard by a representative of Capitol Records. In spite of an offer to record in Los Angeles, the group held out hope that they could record in London, the recording home of their heroes, The Beatles. In 1968 they traveled to London twice, receiving offers from both EMI and Decca. In 1969, the band returned to London and recorded an album at EMI studios, now known as Abbey Road. Guitarist Bob Frank, an original member of the band, left the group just before they went to London to record, due to personal issues. He was replaced briefly by Phil Edholm, a guitarist introduced to the group only a few months before leaving for England. Unfortunately, he did not work out as well 
and was released by the group soon after arriving in England. Once the album was finished, the band returned to St. Louis where more personal problems between a group member and his family caused the group to splinter. EMI decided not to release the album. EMI invited Tom Hartman to come to England and restart, but Hartman felt that moving to England was too great a step at his age. The partnership with EMI was then dissolved. The album was not released until a CD release in 2003 by RPM. The album was engineered by Beatles' engineers Norman Smith, Geoff Emerick, Phil McDonald, and Alan Parsons, who also played recorder on one of the album's tracks. Members
