The breathless title aside, it's hard not to recommend The Best Tango Album in the World Ever. It's two discs of Argentina's stately national dance music, delivered by luminaries such as legendary vocalist Carlos Gardel (on two scratchy tracks), innovative composer Astor Piazzolla (one track, and a version of his "Adios Nonino" by the Sexteto Mayor), and others. That means that dancers will have all the inspiration they need for a night of ochos on the dance floor. Enthusiasts of the music get colder comfort, though: scant liner notes, no recording dates -- the usual for this kind of crowd-pleasing, catalogue-clearing project. But with 30 tracks of crisply recorded drama, it's a great jumping-off point for the casual fan.
