There is a long-standing jazz tradition of reinterpreting pop music favorites. John Coltrane’s version of “My Favorite Things” may be the most famous example, but there are hundreds, if not thousands, more. One of the latest features saxophonist Dave Koz. He teamed up with Postmodern Jukebox keyboardist Scott Bradlee for a jazz quartet performance of the “Game of Thrones” theme song, which is appropriately, if not imaginatively, named “Main Title” on the original soundtrack recording. The tune lends itself well to jazz interpretation. With a prominent bass line, hummable melody and 6/8 time signature, there is plenty of room for Koz and Bradley to stretch out, though they don’t venture too far into uncharted territory.
