Cliff Burton on Master of Puppets: bass solo, Orion and the last album

Cliff Burton on Master of Puppets delivered the Cliff Burton bass solo on Orion that fans still cite as the album's emotional peak. Master of Puppets is Cliff Burton's last album with Metallica before the 1986 tour bus accident.

The Cliff Burton bass tone on the record was tracked direct with a wah pedal and an overdriven amp, a setup Burton had used since Ride The Lightning. Several takes were kept against the engineer's recommendation because the imperfections matched the song's intent.
