Celtic Frost bassist Martin Ain suddenly passed away at the age of 50 last year, and now Metallica is paying tribute to Ain's legacy live. Metallica threw in a cover of Celtic Frost's "Procreation Of The Wicked" at a show fittingly in Geneva, Switzerland, and with bassist Robert Trujillo absolutely slaying the vocals.
This cover has made me realize two things about Metallica – they could do a covers album of heavier stuff with Trujillo on vocals and it would probably rule, and that Trujillo should probably lend more vocals to the band in general.
