I attended the recent exodus gig in belfast,which was a good live show,,n a privilage to see the old school members in action,holt on guitar was amasing........what im wondering is,does anyone know where i could get my hands on a used ticket for this gig,for collectable reasons????????,,big thrash metal fan..i paid on the door on the nite,so did not get an actual ticket

major respect to gary holt and tom hunting
