Ive seen this band at a recent local music festival and they were actually quite good. They definitely aren’t in the traditional realm but have their own unique sound. Ive been a guest on this forum for a good while and just decided to create an account… . What do you guys think?

Considering the crazy fast speed of all 4 tunes I’d go with… Jam Grass? :huh
