The rockers played an intimate gig at the Fillmore in San Francisco and the 1,200 fans who packed into the venue were thrilled with the special three-hour set, which included a number of the band's lesser-known songs.
It was the first of four shows at the concert this week and a pass to see all the gigs was $19.81 - a figure that honours the year the band formed - while individual shows cost just $6.
Longtime fan George Good said: "I'm as happy as a clam. They could've charged me $800 and I would've bought it."
They also played 'Hate Train', a previously unheard track from the sessions for last album 'Death Magnetic and covers of 'It's Electric' by Diamond Head and 'Please Don't Judas Me' by Nazareth.
Jason - who left the band in 2001 - joined the group to featured on 'Harvester of Sorrow', 'Damage, Inc.' and show closer 'Seek and Destroy'.
