I think we just saw Suicide, or possibly A Split-Second. Drummer seems in literal trance; Dalek involvement indicated. Developing...
Drummer's faces are hilarious, the guy drumming for Roots Manuva the other night alternated between looking incredibly angry, or like he was doing a massive poo.
This guy didn't have the usual Drummer Face, though -- most of the time his eyes were closed and his head didn't move at all while he wailed away.
I saw that same face on a guitarist doing a tough solo. Eyes unfocused, and no movement at all except for his hands flying across the strings.
Funny, when a pretty girl started dancing at the front of the stage on the next song, he looked a lot more interested!
