 On May 11 , 2011 , Down announced on their Facebook page that they " demoed a brand new tune . " Down played at Download Festival on Saturday 11 June 2011 . They played alongside System of a Down , Avenged Sevenfold and Alice Cooper . Rex did not tour with Down during their spring 2011 shows . Crowbar bassist Pat Bruders filled in for Rex during those shows . " Rex is not gonna be with us , " said Keenan . " He 's got things he needs to deal with , and we gave him an ultimatum and he 's trying to work things out . We 've got Pat ( Bruders ) from Crowbar playing bass , and he 's ass @-@ kickin ' in the same way . He plays with his fingers — which is really cool ; he 's got the whole Geezer Butler thing going on . " When asked whether or not Brown was still considered a part of the band , Keenan was hopeful but hesitant : " I don 't know what to really say on that ; he 's not out of the band , but he 's not playing with us live . " On June 22 , 2011 , Jimmy Bower announced that Rex Brown would not be returning to Down , and that Pat Bruders is his replacement .
