Bucking up and buckling down for its fourth full-length, Texas's White Denim is an outfit that has proven to be as versatile as it is stylish. The addition of a second guitarist in the form of Austin Jenkins has brought new levity to a threesome propelled by singer/guitarist James Petralli and reinforced by a powerhouse rhythm section furnished by drummer Josh Block and bassist Steven Terebecki. Working and touring together since September of 2010, the psych-blues crusaders returned to the studios ready to go all-in for their fourth full-length release, appropriately titled D.

A 37-minute masterpiece hung on the hooky single "Drug," D abounds with gentle multi-sonic layers that float on the summer breeze like so many sheets hung out on the line. "It's Him" introduces the listener to the high mountain meadow of White Denim's dreaming; here Petralli's mental clutter cascades over a lyrical landscape as if spilled from the back of My Morning Jacket's open tailgate. While "Burnished" seems remarkably free in its Zeppelin-esque phrasing, "At the Farm" shows off the band's eerily intuitive sense of timing with deliciously distorted strings and vocals that buzz around like so many bumblebees fuzzy

on nectar.

Now equipped with a solid fourth member and admittedly superior technology at its disposal, these nature children have somehow managed to go full-out organic, pulling out the rawhide hats and picket-fence smiles and issuing forth a magnificent spillway of Jethro Tull flutes and psychedelic guitar squalor.

Whether splashing through puddly riffs

and acid-pulsed percussion that patters like raindrops over a mushroom cap,

as on "River to Consider," or collapsing into intensely introverted Fugazi-calibre breakdowns on "Anvil Everything," White Denim ultimately sounds like no one but themselves. Clinical and ethereal.
