Metallica bassist Robert Trujillo discussed the importance of the groove factor in Metallica, telling Polar Music in a new interview (transcribed by Ultimate-Guitar):
“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 one of the best drummers in the world, on his guitar. Because he is really a groove machine. with that instrument.
“It’s an unusual combination of players [in Metallica] but it words – everybody’s unique and different in their own way and we come together and do what we do. And I think that’s what the crowd feels when they see us or hear our music.
“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.”
