Really Weird Musical Combinations

My public radio friend called this morning with a new Rhapsody blues listing this week.  Billed as blues plus celtic, the Japanese trio Harmonica Creams has a new listing for TOKYO LIVE SMOKIN'.  Here is their bio http://harmonicacreams.com/#about  Of course there are some YouTube videos out there.

I have seen some well-done pairings at Merlefest with Afro-Celt Sound System and Del McCroury band with Preservation Hall Jazz Band but the combination of blues harmonica and celtic music (with maybe a little touch of newgrass) is kind of mind-boggling.

What unique combinations are in your library?
