Does Dave mustane sing ride the lightning?

Answer 1

Dave Mustaine NEVER sung a single word in Metallica, and only recorded their first demo "No Life 'Til Leather"

The actual guitarist for Kill 'Em All was Kirk Hammet, but the riffs were written by Mustaine before he was kicked out of the band for being an alcoholic.

James Hetfield definitely sung Ride The Lightning, as well as every other Metallica song.

Answer 2

Dave Mustaine never recorded any songs with metallica besides the during the demo "No Life 'Til Leather"
