Known by a select few as one of Canada's most intriguing cult artists, Bruce Haack always strived for mainstream acceptance. But Haack's true ambition may have been fully realized when it was discovered that he left behind a whopping 213 reels of recordings after his death in 1988. Preservation Tapes confusingly collects just ten of these tracks, with the majority coming from a session recorded for American Christian label, Sparrow Records, during his creative peak in the early '70s. In 2016, after reissuing two Bruce Haack albums, Haackula and Electric Lucifer Book II, Telephone Explosion began speaking with Ted Pandel (Bruce's lifelong friend and business partner) about working on the 1970 masterpiece The Electric Lucifer. It turned out there was another matter that he wanted to discuss: finding a final resting place for the Bruce Haack archive. We were shown test-pressings of The Electric Lucifer board mixes from his Columbia studio sessions, countless pieces of written music, a large number of personal photos, an invitation from Raymond Scott inviting Bruce to play his newly created Electronium instrument (now owned by Devo's Mark Mothersbaugh), poems, press clippings, and, most importantly, a heavy-duty shelf containing 213 reel-to-reel tapes.

All of the chosen material on The Preservation Tapes is unreleased, has only been heard by a handful of people and showcases a relatively unknown period in Bruce's musical career where Bruce was recording for Sparrow Records (who billed themselves as 'America's best Christian music record label'). Bruce's signature Farad vocoder continues to feature prominently, but the lyrical content is decidedly more religious. The Bruce Haack archive is now resting in the Provincial Archives of Alberta, in Edmonton, Alberta, Canada.
