Well, let's switch genres.

Try some Streetlight Manifesto; much of their music is done on a five string. Look up Everything Went Numb in particular. Very good song.
I play guitar in a ska band.
Modded MIM Strat > Fender Tuner > Bugera V55HD > Custom built 2x12
If want to downtune, then most Between The Buried And Me songs from the Alaska album onwards.

Informal Gluttony is great fun to play and isn't TOO difficult.
