Me and my friend back home started a instrumental band with a lot of experimental aspects (I play guitar, keyboard, and extra percussion during drum-heavy parts). My friend today recorded 4 different demos for a future 4-part song, each part a different style. It is mainly a tribute to the show Perfect Hair Forever and I want to get some UG feedback on his riffs. The songs are on my profile.

Note: He uses a loop pedal to create rhythm parts and then solos over them.
