Often when I recommend people something, when they try to venture into this music, I suggest they start at the rock spectrum (or any other popular music spectrum). It's accessible because it's still familiar. There are enough avant garde/experimental tendencies that it transcends the genre, but not overwhelmingly so to break it all apart and create something completely new, and therefore unknown and scary.
Early Swans/Sonic Youth, no wave and kraut rock was my ticket. Personally I find repetition very accessible, so kraut rock was always appealing.
So I wanted to post
Neu! - Negativland, but it's blocked in my country. Ah well, I hope it works for the rest of you (who still haven't heard it)
