This week, hosts Bob Boilen and Robin Hilton play brand new cuts from springtime releases by the well-established and widely adored bands The Black Keys and Swans. Both songs are instantly recognizable: The Black Keys for their spare, punchy, guitar-based pop, and Swans for their epic, densely layered orchestrations. Bob shares music by a New Zealand-based band called Tiny Ruins. That song's airy vocals and restrained instrumentation pair well with a pick from Robin: Dylan Shearer, who channels the folky, quiet side of Pink Floyd on a song called "Meadow Mines (Fort Polio)." Also on the program: The strangely alluring electronica of London's Metronomy; and Robin mourns the loss his beloved Jayhawks suffered over the weekend in the NCAA basketball tournament with the soothing sounds of A Winged Victory For The Sullen.   Minuet For A Cheap Piano No. 1 Artist: A Winged Victory for the Sullen Album: Atomos VII   A Little God In My Hands Artist: Swans Album: To Be Kind   Meadow Mines (Fort Polio) Artist: Dylan Shearer Album: Garagearray   Ballad of the Hanging Parcel Artist: Tiny Ruins Album: Brightly Painted One   Boy Racers Artist: Metronomy Album: Love Letters   Fever Artist: The Black Keys Album: Turn Blue
