I know plenty of songs on guitar and have a bunch of tunes written. I just have to EQ them properly before putting them up on this site, so that's why my discography looks sparse.
Other than that, I'm not going to tell you all the songs I can play... but Himsa's "Big Timber" is probably the hardest song I can play on guitar w/o probs. Other than that, it's taking me a long time trying to get Black Dahlia Murder's discography up to speed. I've got all the notes memorized, just have to keep at it with speed training.
