Must agree with you guys that the Mars Volta rock the house. But ATDI wasn't better. They had more complex vocals (with more singers and hence more harmonies), but the sound was a lot more unrefined. I like ATDI, and I like the Mars Volta. But I think the Mars Volta has a much more refined sound, and that's why I like them more. My favorite song is "Cassandra Gemini" (all of the parts!).
