I don't really know new songs per se, as I'm always listening to my Little Walter, and Sonny Terry, and Sonny Boy Willaimson collections [that I picked up from Amazon cheap! ]
But if you watch any programs on TLC, Discovery, or History Channels - well there's a whole lot of harpin' going on there!
Really! Anything with Mike Rowe - Dirty Jobs and Deadliest Catch, even some Ford commercials; then American Chopper; American Pickers; Pawn Stars; and the list goes on and on - I listen for the blues harpster(s) playing in the background music.
I don't know if any of them are Howard Levy gigs; and the credits go by too fast to find out who they are...But I'd like to play like them and just riff as they do!
Hopefully, some day soon I can do something as good as them; I'll keep you posted, but don't hold your blues notes for too long, eh?!
In the meantime, keep on harpin' and thanks for reading!!
