I feel kind of stupid for having thought they were a relatively new band. First I'd ever heard of them was when I downloaded The Glamour Kills Spring Sampler last year. And yet I still can't find any albums from them other than Wilder Child D:
It doesn't go back much further back from My Life with a Giant on the internet, but they have early stuff in the vain of Blink 182 style pop punk from 03-06(?) with different members over the years. Wilder Child is a good representation of where they're all at in life now with members set in stone.
