may videos sa youtube na tugtugan sa kalye gamit na set improv lahat. pedals lang yata ang tunay.
and yea, i remember when i used to hang out with a bunch of old 'tallica fans na yung buong drum set(bukod sa hi hat at pedals) ay improvised. yung amps ay panasonic na karaoke na umiilaw pa yung bass dome to indicate peaking. some worn out DOD distortion pedal, upuan, mic na buka na yung dulo, at sangkatutak na desire to play the music they want - you get a three-piece combo playing old metallica tunes!
