The American heavy metal band Slayer embarked on their first national tour in 1984, following the release of their debut three song EP.
Records available online are unclear, but the band played between one and three shows in Houston. Following one of the shows, the band visited the KPFT studio and took over the mic for an uncensored call in segment during The Random Sampler.
In December, 2022 YouTuber UGLY AUDIO posted the full interview as aired at https://youtu.be/jeI_cQBdPrY and an audio copy is embedded here:
Strong language ahead:
http://www.chmetal.info/tourdates/Slayer_1984.htm and https://www.concertarchives.org/venues/casino-ballroom give the date as December 2, 1984 at the Casino Ballroom but a ticket stub from another show places the band in Houston on June 2, 1984 as well.
