I've heard a lot of different versions of Ramin Djawadi's Game of Thrones theme in my day—like this one—but never a rendition this smooth.
Here we've got saxophonist Dave Koz sitting in with pianist Scott Bradlee's trio, putting the G - Am - E in Game of Thrones. (I have no idea if those chords are actually in this arrangement, don't email me.) They turn the theme into a nice uptempo 6/8 kinda thing, with plenty of room for improvisation. Nice.
Hopefully sheet music for this arrangement will surface, and high school jazz concerts will never be the same.
