What music clears your mind?

Certain music has a spiritual quality to it that seems to speak to me on a primal level. It inspires, lifts, and ignites the senses. This kind of music makes me feel high(er), no matter what language or genre.

What (preferably obscure) music have you found that does this for you? Also, feel free to discuss the ways music affects/ has affected you (on drugs or not!).

Some artists that do this for me are Shpongle, Cheb i Sabbah, Bluetech, Afro Celt Sound System, and Tycho Brahe.
