Hammett reached the subject while discussing METALLICA‘s 1984 track “Trapped Under Ice,” which uses riff Kirk originally wrote for EXODUS song “Impaler.”
“They [the riffs] came from songs I had written, the music I had written. I consider them my parts,” Kirk said. “I didn’t feel guilty about that, but I did feel guilty about leaving the band I started in high school. I’ve known [EXODUS drummer] Tom Hunting since I was 16 years old, I’ve known [EXODUS guitarist] Gary Holt since I was 17. We’re all close to this day, but there was a lot of guilt there for a while.
“A little bit of remorse,” he added. “But I really felt that METALLICA was my calling. I felt more comfortable playing in METALLICA than I ever did in EXODUS, so go figure.”
METALLICA‘s latest album, was released as a double album in November 2016. It is their first studio album in eight years following 2008’s Death Magnetic, marking the longest gap between two studio albums in the band’s career.
