This was one of two Jethro Tull albums released using quadraphonic sound (the other is ''War Child''). One difference between the actual album and between the quadraphonic version was that the song "Wind Up" was preformed in a higher key (this version is included in the re-release). Also, the song "Aqualung" has two riffs at the begining of it instead of just one in the quadraphonic version. | This was one of two Jethro Tull albums released using quadraphonic sound (the other is ''War Child'').
