I only recently found out about this band, but I really dig their sound. Like, a lot.
Skinny Girl Diet is three teenage girls from London playing riot grrrl/post-punk music, and it's really quite fantastic. Plus they sing about mermaids!
They have a tumblr account with links and stuff. Also, here are a few songs I really like of theirs:
Sunburn by Skinny Girl Diet
Insomnia by Skinny Girl Diet
I guess I just envy them. I've always wanted to be in an angry girl band... I want to kick and scream and yell about how much boys suck and I wanna beat them all up. Plus these girls are really pretty and yeah.
