Jay-sus, man. Lots of changing musical drum thrones lately in terms of endorsements. Sonor and Tama are the big losers here as Thomas Lang and Dave Grohl jump ship to sign on with DW. Also joining them in Drum Workshop’s ample, woody bosom are extreme metal master Derek Roddy, Creed stickman Scott Phillips, studio legend John J. R. Robinson, and Muse drummer Dominick Howard.
