Formed in Toronto, Canada, in the late 60s, Heat Exchange are known for their three fantastic 45s for the Yorkville label - released in the early 70s - on which they mixed hard rock with psychedelic, heavy progressive and funk-rock sounds. So it was a major surprise to discover that in 1972, the band recorded more stuff with the intention of releasing an album. But in the end, the deal fell through and only four of those tracks were released as part of their 45s. Soon after, the band disbanded.
