This might not sound like much, but seeing how deceptively complicated a lot of their music is I'm always amazing seeing some of those songs stripped down to see all the different parts. A multi-instrumentalist playing guitar, piano, keyboards, electronics, drums, and a producer.

I've listened to Morricone since a was a little kid when my dad used to play some of his soundtracks from the 60's I now find myself actively seeking many if his works out they are truly amazing. Hearing his compilation called High always as rounded me and was and still is one of my favorites.
