Paul Baloff (April 25, 1960 – February 2, 2002) was an American singer, most notable for his time in thrash metal band Exodus.
Stephani Danelle Perry (credited as S. D. Perry in her works) is an American novelist.
 She is the daughter of writer Steve Perry.
Stephen Henry Perry (born October 8, 1963) is an American musician, best known as lead singer, songwriter and rhythm guitarist for the Oregon ska-swing band the Cherry Poppin' Daddies.
Arrival is the eleventh studio album by the American rock band Journey, released in the United States in 2001.
 A version with one substituted song was released in Japan in 2000.
 The album was the band's first full-length studio album with new lead vocalist Steve Augeri, who replaced popular frontman Steve Perry, and with Deen Castronovo, who replaced Steve Smith as the band's drummer.
Bonded by Blood is the debut studio album by the San Francisco thrash metal band Exodus.
 Although the album was completed in the summer of 1984, it was not released until 1985 due to issues with Exodus and their record label.
 It is considered one of the most influential thrash metal albums of all time.
 It is also the only full-length studio album of Exodus to feature Paul Baloff on vocals, though he was also on their "1982 Demo".
 Baloff was back in Exodus for five years (from 1997 to his death in 2002), and appeared on their 1997 live album "Another Lesson in Violence".
Paul Taylor (born June 4, 1960, San Francisco, California), formerly credited as Paul Horowitz, is an American musician, who is best known as the keyboardist/guitarist with the late 1980s and early 1990s rock band, Winger (1987–1992, 2001–2003, 2013–2014, 2014–present).
 Although he is perhaps most frequently associated with Winger, Taylor has also played with numerous other prominent musicians, including future Sammy Hagar and Boston guitarist Gary Pihl (in his early days), Eric Martin (solo artist and future Mr. Big frontman), Aldo Nova, Steve Perry of Journey, Alice Cooper and Tommy Shaw.
Kill Yourself: The Movie; the bulk of the footage on this DVD was shot during the S.O.D. promotional tour for Bigger Than The Devil in Japan and the United States, interspersed with footage from various events, such as some 1999 shots from the Dynamo Open Air in the Netherlands.
 Also appearing on the DVD are Dimebag Darrell (of Pantera fame), Paul Baloff (of Exodus fame) and Kerry King (of Slayer fame).
The Cherry Poppin' Daddies are an American band established in Eugene, Oregon in 1989.
 Formed by singer Steve Perry and bassist Dan Schmid, the band has experienced many membership changes over the years, with only Perry, Schmid and trumpeter Dana Heitman currently remaining from the founding line-up.
David R White (born David Godfrey) is an American heavy metal lead vocalist who is best known for singing in the thrash metal band Heathen.
 Having stints in underground thrash bands Blind Illusion and Laughing Dead, he joined Heathen in 1985.
 He was ousted from the band in 1989, replaced by Paul Baloff, but returned that same year, performing on both of their LP's, "Breaking the Silence" and "Victims of Deception".
 White immediately stood out from the thrash metal crowd with his operatic, high pitched singing style.
Testament is an American thrash metal band from Berkeley, California.
 Formed in 1983 under the name Legacy, the band's current lineup comprises guitarists Eric Peterson and Alex Skolnick, lead vocalist Chuck Billy, drummer Gene Hoglan, and bassist Steve Di Giorgio.
 In the 34 years since its inception, Testament has had numerous lineup changes, and Peterson has been the only constant member.
 Billy replaced former singer Steve Souza (who left the band to join Exodus as the replacement of Paul Baloff) in 1986, prior to the recording of their first studio album, "The Legacy", and has been a member of the band since.
 Peterson and Billy are the only band members to appear on every album.
