Is that Danny Trejo?!?!  This week's guest on Discover New Music is Wolfgang Van Halen of Mammoth WVH.  The band's third studio album "The End" drops on October 24th.  Wolf says this record felt so much more comfortable and confident in terms of who Mammoth WVH is and wants to be as a band.  Plus, Wolfgang talks about shaping and challenging himself as a songwriter, but still enjoying the playing side of things...bass, drums and guitar!  And, he breaks down the epic music video for the record's title track "The End."  As always, a quick round of Rapid Fire is played...he picked Bowie over Roth.
