I don't know much about drums (typical guitarist) but he seems to be solid as a rock. There was some comment about him having a different/sharper attack on the drums than Paul on another thread.I just like the fact he smiles loads!
There's some great vids on YouTube added on since Moon's contributions. Check out 'Mean To Me' and 'Fingers Of Love'. The camera is quite a way back but the sound is clear as a bell.
Matt's drumming shines through!
