Five-O were an hardcore influenced emo band in the early 90s from Arizona. I don't really know that much about this band, but as far as I can tell they didn't release much. Five-O released a demo in 92, Fall Through 7" in 93 and a s/t 7" 95. I only have Fall Through but I'll see if I can find their other stuff.
Anyway, enjoy.
