I just stumbled across this fabulous CD, Tango Fiesta. Only snippets of each track on the album are available, but it's enough to draw you in. The music is gorgeous, a fabulous, relatively modern fusion of all sorts of stuff, underpinned by the unmistakable, irrepressible tango beat. It's a compilation by musicians from across the world, each of whom brings their own "flavour" to traditional tango. There's a review here. The composer Gus Flaherty is a genius.
