It's definitely an album that works best listened to whole. Even better than that though, in my opinion, is Nikolai Kapustin's album Piano Music, which is just amazing. Also, not all third stream is piano music by any means. Check out Bill Russo's School of Rebellion for more a full band, horn-based take on the style.
