USA: Late 1978/early 1979
Source: Sides 1 – 4 (tr.1 only) KZOK Seattle FM Broadcast “OK 102.5 Seattle In Concert” FM recording from the Aquarius Tavern in Seattle (formerly known as Parker’s Ballroom), summer of 1975 (the date was usually stated as June 1st – update: Based on an ad in the Seattle Times, the actual date was likely July 18, ’75). The venue has been confirmed due to the inclusion of two tracks – “Mother Earth Blues”and their cover of Kiki Dee’s “I’ve Got The Music In Me” – on their official MAGAZINE album in 1978. It appears that multi-track recordings were made that night and the bootleg sounds excellent.
The source for tracks 2 & 3 on side 4 “Devil Delight” and “Battle of Evermore” is unknown at this time. Please leave a comment if you know more.
Heart’s debut album Dreamboat Annie was released in Canada in the summer of 1975 but would not see a US release until the coming year and the band was playing showcases in certain markets to drum up radio interest.
