"We're happy in pieces/Happy in bits," sing Suzi Horn and Tobin Prinz of the Portsmouth, England duo Prinzhorn Dance School. They might be talking about their emotions; they're definitely describing their music. Prinzhorn's second album is all about pieces and bits – fragments of rhythm and melody, a bassline chunk here, a snare drum shard there – arranged and rearranged like a jigsaw puzzle. When the pieces slot together, the result is ingeniously minimalist art-pop: "The Flora and Fauna of Britain in Bloom" combines Horn's thrumming bass, Prinz's kickdrum, a sinisterly pealing guitar, and a mordantly monotone vocal into something spooky, transfixing, and (intentionally or not) hilarious. Clay Class is nearly an indie classic. All that's missing are tunes—not quite enough of those bits.

“Ambling Alp”

The "Ambling Alp" was the nickname of the six-and-a-half-foot-tall Primo Carnera. Though the song is named after the Italian-born 1930s heavyweight champion, Yeasayer are actually paying tribute to boxing legend Joe Louis with this first-person psychedelic dance-rock tune. “I was always interested in writing a song that had boxing mythology in it,” Yeasayer’s Chris Keating said. “It’s pretty fascinating: There were so many amazing characters, and it was so closely entwined with 20th century history.” Yeaseyer also invokes German champ Max Schmeling and hints at the historical significance placed on the historic bouts between the Nazi-era boxer and the African-American Louis.
