It seems to me that it would be particularly useful to try to consolidate "what did artist A use on song/album B?" threads to one. And also because I have such a question and would like to contribute more than just another question.
I want to know how Matt Bellamy got the sound at the intro of "Map of the Problematique". It bugs me every time I hear the song. Part of me thinks it's just two-handed tapping with some studio trickery to make it sound more staccato.
