Billboard premiered a song from Johnny Winter’s final album, Step Back which features Aerosmith’s Joe Perry. The blues-rock legend passed away on July 16th at the age of 70 while on tour with his band in Switzerland.

“I listen to the album, and it’s as if he’s still standing there,” producer Paul Nelson tells Billboard. “The album was already great without this tragedy. Johnny knew this. He worked and got healthier and he had come back. Then the tragedy happens — we all went to the funeral, then two weeks later the whole album release takes over. It’s all happened so fast.”

 Joe Perry isn’t the only big name on the album, Eric Clapton, ZZ Top’s Brian Setzer, Leslie West, Dr. John, Joe Bonamassa, Ben Harper, and many others play alongside Winter on Step Back. According to Nelson, when Perry was asked to play on the album he replied, “Paul, you don’t understand what this means for me. I wouldn’t have picked up the guitar if it wasn’t for Johnny.”
