Metallica’s bassist Robert Trujillo was recently interviewed by Polar Music and he talked about the groove factor in METALLICA:
“I’ll go back to Jaco Pastorius, ’cause it was always about the groove. No matter what he was playing, whether it was a ballad or a bebop song or something really funky, there was always the groove. And it’s the same with METALLICA.
“I always say James Hetfield is the best drummers in the world, on his guitar. Because he is really a groove machine. with that instrument.
“The new album [‘Hardwired… To Self-Destruct‘], to me, is interesting because there’s really a powerful presence in the rhythm section, which is really exciting.”
