If you caught Annihilator at Bloodstock Open Air, then you got to hear a new song called "Twisted Lobotomy." The song is predictably thrashy and damn near impossible on guitar, and is expected to appear on Annihilator's followup to 2015's Suicide Society due out at some point possibly later this year.
In the meantime, enjoy the song! Which is not the worst audio quality in the world, thankfully.
