“(Gimme some of that) Ol’ Atonal Music,” by the singer Merle Hazard, details in sunny and endearing tones a love of atonality, while explaining to newbies what that is (music that isn’t in one clear key), and includes the best atonal banjo solo you’ve ever heard (probably the only atonal banjo solo you’ve ever heard). That the solo, and the production values, are so good, is no surprise: The soloist and the recording’s producer is Alison Brown, one of the leading five-string banjo players in the country. Combine that with a crack backup band, Hazard’s sweetly earnest delivery and a John Cage spoof that’s actually funny, and you have a lot of people laughing at their desks. – Washington Post
