Keane, 'Perfect Symmetry' (Interscope)

Wimpy balladeers experience a rush of blood to the head.

News flash: Coldplay aren’t the only dreamy British pop-rock band with an experimental streak. On album three, Keane trick out their pretty piano melodies with tasty synths (“The Lovers Are Losing”), booming rap beats (“Spiralling”), and fuzzy new-wave guitars (“You Haven’t Told Me Anything”).

Todd Snider, 'Peace Queer' (Aimless)

Resilient roots rocker rages (subtly) against the machine.

One of roots music’s slyest, smartest songwriters, Nashville-based Todd Snider isn’t up to the usual protest-song ploys on this eight-song mini album (which nonetheless protests plenty): “I did not do this to change your mind about anything,” he explains in a spoken interlude.

The Secret Machines, 'The Secret Machines' (TSM)

Former Next Big Things offer the newest new wave of metal.

Leaving Reprise after two commercially inert, if artistically compelling, albums and losing guitarist Ben Curtis (who founded the group with brother Brandon), this Brooklyn-based trio return like Gary Numan on a hard-rock bender.

The Mighty Underdogs, 'Droppin’ Science Fiction' (Definitive Jux)

Lords of the underground settle in for a B-boy bull session.

As the stalwart indie MCs now performing under the name Mighty Underdogs, Lateef (from Latyrx and Maroons) and Gift of Gab (from Blackalicious) sling rhymes with effortless wit and style.

Ray LaMontagne, 'Gossip in the Grain' (RCA)

Acoustic chronicler of dark side cracks the window a tad.

Well respected for sparse, plaintive bummer folk since his 2004 debut, LaMontagne gets a bit more expansive here, gently juking his earthy rasp with Stax-y horns, guitar twang, and lilting lady backup vocals.
