Sound Hole were formed toward the end of the 1960's, possibly in 1967. The group was originally Wide Hole, a high school band that included Mario Cipollina, Bill Gibson and John Farey. Brian Marnell joined the group on guitar and they started to play at local Bay Area venues opening for bigger groups. Other members of the group at various times during the late 60's and early 70's included John Colla, Brian Hogan, Bruce Gapinski and Gregg Gavin.
In the early 1970s Sound Hole became Van Morrison's back-up band, performing with him in 1973 and 1974. Sound Hole continued playing with some personnel changes until 1977 when they evolved into Airplay. The group only recorded one single, toward the end of their existence.
