Metallica's current lineup comprises founding members and primary songwriters Hetfield and Ulrich, longtime lead guitarist Kirk Hammett, and bassist Robert Trujillo.

As with Rage Against the Machine, the band prided themselves on the fact that all sounds on their albums were produced using only guitars, bass, drums, and vocals, with emphasis on Cornell's wide vocal range and Morello's unconventional guitar solos.
