Wavelength was recorded at the Manor in Oxfordshire, England over several months and completed later, at Shangri-la studios in America. Morrison had brought together musicians that represented almost all phases of his musical history to date: Herbie Armstrong from his showband days in Belfast, Peter Bardens from Them, Garth Hudson from The Band and Peter Van Hooke who had worked with Morrison a few years previously. He also added guitarist Bobby Tench from Streetwalkers. The songs on this album recall various stages of Morrison’s life. “Wavelength” recalled fond memories of his adolescence, listening to the Voice of America.
