Heat Exchange

Heat Exchange was a Canadian rock band who had evolved out of a late 1960s, blues quartet. They had a hit in Canada in 1972 with "Can You Tell Me". Nearly five decades later they would finally have their album released.
Background
They started out as Cloud, a four-man blues group that Neil Chapman had founded in the late 1960s. The lineup then was Neil Chapman on guitar, Marty Morin on Drums, Gord McKinnon on keyboards and Ralph Smith on bass. They later expanded the group by inviting in Craig Carmody on sax and flute and Mike Landford on vocals. Later they had to change their name due to another band with the similar name, The Clouds who had released an album. Thinking that the names were too similar, the name chosen was Heat exchange.
They were almost signed to the RCA label but Yorkville Records gave them a better offer. Subsequently, the group were signed to the label.
