Before Judas Priest recorded their first album, a second guitar player, Glenn Tipton, joined the band. The first album, Rocka Rolla, came out in 1974. It was not very successful, probably because it didn't have many of the songs that the band were known for playing in live concerts back in those days. They would later be on the band's next album, Sad Wings of Destiny in 1976. That album was followed up by Sin After Sin in 1977. These three albums had a hard rock style that was familiar to bands like Led Zeppelin, and had a psychedelic feel.
