I found out about ratatat through some random surfing. I dont know much about him, but hes a producer and remixer and I like his style!
But what really caught me were these videos on his site. They both have a very simple effect added to the exsiting clip, repurposing it into somethign startling, and bizarre.
I recognize the paul simon video, but not the first one.
And from his myspace, you findAudio Dregs, a record label and DIY music and art collective with a myspace page worth checking out!
