I too took lessons from Darren. Great player, but couldn't play the same thing twice in a row without making a mistake, which explains why the two solo guitar two handed pieces on his first album were the actual 8 track home demos, he couldn't do it in the studio. He also seemed to have a problem with any of the other guys on the scene that weren't Shrapnel guys. He idolized Paul Gilbert, hated George Lynch and Zakk Wylde, etc. Weird guy. Got caught up in some nefarious business dealings with his Psycho Pharma supplement brand later on.
