I was checking Imogen’s MySpace and found out that a cellist called Zoe Keating is supporting the Brighton Gig on April 5th. The technique is very similar to Bela another loopy cellist (see my post from October) but from the samples on the web site, slightly less less angry.
Check out this video clip of the song TetrisHead beautiful music beautiful visuals (and nice web design too).
I wonder if Bela will be at the gig? She responded to my last posting, so Bela looking at your schedule it actually fits in quite nicely for you.
