I first heard Koop on Radio Paradise (via iTunes), where the first two cuts from Koop Islands are in rotation. This album is kind of '40s swing with an occasional Caribbean spin and some very modern lyrics. Since getting this, I've bought Koop's other two albums, and also sent this album to my 78-year-old uncle for his birthday. And I deeply regret missing Koop when they played recently at Bimbo's 360 in San Francisco; I just hope I can catch them live soon.
