One night, Canadian artist Leif Vollebekk dreamt that Jeff Buckley taught him a song in a Manhattan rehearsal space. Vollebekk watched Buckley’s hand on the fretboard of his guitar as he followed along. Vollebekk felt like he was in heaven, as their falsettos rang out. When he woke up, he wondered which Buckley song that might have been. He quickly realized that it was “Rock and Roll,” his own new song.
