The list of songs John did with other musicians, minus full albums he plays on; those are treated as collaborations. The two earliest appearances on The Mars Volta albums have been cross-listed on the page containing all of John’s releases with the group. If John was featured on more than one song, the album name will be shown as a title, with track name in the notes. If he was featured on just one song, the title will be just the name of the track.
Please, note that you cannot click through on any of the releases at this time. This option will be available again, soon.
