Havok is fucking rad. Have loved them for a while. Their middle albums are their best work, IMO, with "Time Is Up" being at the top. Honestly feel their last couple albums have been slowly going downwards in wiriting, as it seems David is leaning a little into the cheese too much for my personal taste, but dude is still a incredibly talented writer, guitarist and vocalist.
Reece is a ridiculously good lead guitarist and a super nice dude. My guitarist and I went to hang with him at a show in Cleveland a few years ago, as he takes lessons from Reece. Couldn't have been a nicer guy, and they put on a hell of a show even thoug there were only about 20 people there.
