Which Metallica studio album was the first to feature Robert Trujillo?

Which Metallica studio album was the first to feature Robert Trujillo? Death Magnetic. Released in 2008, it was the first Metallica studio album on which Trujillo played bass.

Trujillo joined Metallica in February 2003 after Jason Newsted’s departure. He arrived after the recording of St. Anger, so that album does not feature him as its bassist; producer Bob Rock performed the bass parts during its sessions. This timing is the source of the most common confusion about the answer.

Death Magnetic marked Trujillo’s full studio debut with the band and also gave him songwriting credits on every track alongside James Hetfield, Lars Ulrich, and Kirk Hammett. The album was produced by Rick Rubin and was widely viewed as a return toward Metallica’s earlier thrash-oriented approach after the more experimental St. Anger.
