I don't know why this is in HN, but thanks for posting this. I have always loved Bolero for its hypnotic transcendental feeling, that can be found in music of Terry Riley, Arvo Pärt and electronic music. I started to reading about Sergiu Celibidache and he seems a very interesting composer. A teaser from Wikipedia:

"Celibidache frequently refused to release his performances on commercial recordings during his lifetime, claiming that a listener could not obtain a "transcendental experience" outside the concert hall. Many of the recordings of his performances were released posthumously. He has nonetheless earned international acclaim for celebrated interpretations of the classical music repertoire and was known for a spirited performance style informed by his study and experiences in Zen Buddhism. He is regarded as one of the greatest conductors of the 20th century."
