Listened to Heatbox. It's pretty rough, not crazy about the vocals, a bit indecipherable (I understand they're probably in German, but they're low in the mix and bit strained at times) and not much tune going on. Sounds a bit nuts, which is nice, but not much songcraft employed.

So many possibilities, so little ability.

You know you're a guitar player when you tell your father what note he's yelling at you in and then improvise over the top.
the vocals are english...not german
and your songs are not bad...great playing and a good voice
