When Motörhead’s Lemmy Kilmister was still alive, Matt Pike—singer/guitarist in High On Fire and the iconic stoner-metal band Sleep—often found himself compared to the late legend. Once, he even dreamed that Lemmy got mad at him about it. So, three years after the legendary frontman died of cancer, Pike’s Oakland-based sludge trio released a tribute album in his honor. It’s their most diverse—and maybe best—record yet. The riffs are loud, the rhythms are dizzying, and the Motörhead influence is obvious, but it’s still very much a High On Fire album. Land speed record contenders such as “Spewn From the Earth” and “God of the Godless” sit alongside more than 10 minutes of crushing doom in “Sanctioned Annihilation.” The title track, directly inspired by Pike’s dream, pays homage to the late, great Ace of Spades himself. Loud, brutal, nostalgic: Electric Messiah is proof that 20 years in, High On Fire is only getting better.
