Seriously, if you just look at his studio albums you are going to find nothing but pure gold, spanning hundreds of genres ranging from noise to world to trip hop. His distinct voice mixed with his raspy lows and shrilling highs combined with his interesting choices of arrangements makes him completely unmatched in almost any area.
Another interesting aspect is the live show he performs. He uses props, costumes, etc. to really add a completely new level to the show. I saw him on the "Growing Up" tour and we got a whole slew of awesome skits, ranging from PG inside a zorb, to him and his daughter having segway races, to him getting buried in dirt and shit. So fuckin' cool.
I'm blasting his most recent studio release (of original material), Up and am completely blown away yet again.
In this topic we appreciate everything Peter Gabriel.
