Judas Priest Guest Appearances
Aside from Priest's own catalog of recordings, the members also contributed to other artists' projects, and recorded songs for dozens of compilations, soundtracks and tributes. Many of them feature the members in some capacity. The majority of these side projects were released on full-length albums, with a few issued only as singles. In most cases, these records are the only source for the songs, though some contain exclusively live or alternate recordings of Priest's hits.
