 they became a big successful band. And in particular, the beats to their song When the Levee Breaks, those got used all sorts of times in early hip-hop. It's this famous reverb-y drum beat that they did, I believe in like a stairwell or something like that. It's got a really distinct sonic quality to it, and hip-hop artists loved it and sampled it a lot early on. To be exact, the drums are sampled in over 220 songs, from Dr. Dre to the Beastie Boys to Bjork.
