A Calgary band has released its debut album, more than four decades after the final recording session.

Done On Bradstreet recorded the album in New Mexico in 1970, just weeks after opening for Janis Joplin on the Calgary stop of the Festival Express tour. But little did the band know that four decades would pass before they'd even get to hear those recordings.

CBC Radio's Chris dela Torre recently sat down with drummer Bob Everett and singer Lanny Church to talk about the overdue album release.

In 1970, the band recorded with Norman Petty, the famous producer who gave Buddy Holly his signature sound and helped turn Roy Orbison into a household name.

"We were on an all-time high when we went back to Calgary," Church said.

But the album was never produced for various reasons, including a change in band members, and Petty's death in 1984.

"We had never heard these songs, none of us," Church said. "All we ever heard was a short few clips."

Everett and Church recently obtained the master tapes from Norman Petty's museum.

"It's disappointing to know that we didn't get that chance with it," Everett said. "I tell people it was recorded in record time. The mix took a while."
