In case you haven't heard of them, Apocalyptica is a hard-core cello group that plays metal-inspired music with a classical bent. The members all have prestigious classical training but are also metal-heads. The music is really quite amazing, very very powerful but also quite musically valid (it's not just a bunch of noise). To watch them play cellos like they did was incredible, I didn't really think someone could play a cello over their head while head-banging with the music -- cellos are kinda big, you know.
They played a bunch of their old stuff (including covers of some Metallica, their own version of Grieg's Hall of the Mountain King and a whole bunch of their original works) and they also played some of their new album which just came out in January. Unfortunately they weren't selling it at the concert or I definitely would have picked up a copy. The encore was really good too, amazing cover of Enter Sandman by Metallica.
I'm really tired now though so I think I'll go to sleep. Still have to work tomorrow.
