by that title in a book store. In 1983, the band released their first demo, Heavy Metal Insanity, with Matt Wallace serving as producer. According to Mark Osegueda, the group was then "more like a metal band, more like Iron Maiden, Tygers of Pan Tang and stuff like that", as the so-called Bay Area thrash movement was only just beginning to rise to prominence at the time and make its influence felt. Osegueda, a second cousin of the other four members who had been working as their roadie, became the group's lead vocalist in 1984 and performed his first show with the band on a bill with Megadeth in April of that year (at one of the four Megadeth gigs to feature Kerry King on guitars). Death Angel continued to play club gigs in and around the San Francisco Bay area for nearly two years, writing songs and refining their stage show. In 1985, the band recorded the Kill as One demo produced by Metallica's Kirk Hammett, whom they had met at a record store signing in 1983. The underground tape trading wave of the 1980s led to extensive distribution of the demo, bringing the band wide attention. Osegueda later recalled that prior to the release of the band's first album, "We were playing in L.A. and New York, and the crowd was singing our songs, because there was this underground tape trading .... That's what keeps it alive, and I think that's absolutely wonderful." In 1986, Death Angel performed at their Concord, California high school, Clayton Valley High School (now known as Clayton Valley Charter High School), at lunchtime. They famously dedicated the song "Mistress of Pain" to a Vice Principal. The success of Kill as One led to a record deal with Enigma Records, who released Death Angel's debut album, The Ultra-Violence, in 1987. The band recorded the album when all the members were still under 20 years old (with drummer Andy Galeon being the youngest at 14), and subsequently embarked on its first tour, supporting such bands as Exodus, Destruction, Voivod, Sacrifice and Whiplash. A video was filmed for "Voracious Souls", a song about a band of cannibals, but it never aired on MTV due to the nature of the lyrics. Death Angel released their second album, Frolic Through the Park, in 1988. It featured more diverse material than the straightforward thrash of the first album. It
