music, Bostaph joined Systematic in 2003 – a band which he had previously formed with vocalist Tim Narducci and guitarist Adam Ruppel before recording Slayer's Diabolus in Musica. Bostaph introduced the band to Slayer's manager – Rick Sales – to help the band gain notice. As the band needed a drummer in 2003, Bostaph was willing to help out. Bostaph toured with Systematic for four months, although departed in 2004 stating: "I wasn't having very much fun and it's not for me." In 2003 Bostaph sustained an injury to his knee, while playing soccer. After finishing Systematics tour, Bostaph underwent surgery – not touching a drum kit for over a year until he received a phone call from Exodus members. Exodus (2005–2007) Bostaph received a phone call from Exodus' manager, who asked him to join the band. Exodus bass guitarist Jack Gibson talked to guitarist Gary Holt if they should recruit Bostaph – Holt knew Bostaph while Exodus toured with Forbidden, as both bands were from the San Francisco Bay Area. When Bostaph received the phone call, two members had already left Exodus, and drummer Tom Hunting was thinking about leaving. Bostaph knew how to play all the records except for Impact Is Imminent, and recorded drums on the band's 2005 album Shovel Headed Kill Machine. Bostaph asserts the album is different from the band's previous albums; "It's so different because Bonded... was such a landmark record, such a great record that…I watched the band the whole time and I think this is a more, probably, the most brutal record the band has done since Bonded by Blood." Bostaph also says the chemistry between members was very different, due to three out of five members being replaced in one year; "it's a totally different band than before." The band toured for over a year promoting Shovel Headed Kill Machine, and wished to enter the recording studio to record another as soon as possible. However, on March 28, 2007, Bostaph announced that he parted ways with Exodus; "They now have their original drummer Tom Hunting back in the band. I always said from the start if Tom ever wanted to come back, the drum throne is his. I have the greatest respect for Tom and his playing." Bostaph also announced he is no longer endorsing TAMA drum kits, and is proud to represent Drum Workshop and their products. Testament (2007–2011) Paul
