The Chieftains have collaborated with everyone from Ziggy Marley to Madonna, but this 50th-anniversary album is the Celtic traditionalists' first-ever foray into indie rock. The Decemberists' Colin Meloy spins a springy version of Bob Dylan's "When the Ship Comes In," Bon Iver's Justin Vernon croons a ghostly murder ballad, and alt-country bands like Punch Brothers reel 'n' jig it up nicely. Indie rock's cult of schlubby singing doesn't always merge with the Chieftains' crystalline professionalism. So it takes a real pro – Miranda Lambert's roots band Pistol Annies – to truly shake our shamrock; their sumptuously lilting take on "Come All Ye Fair and Tender Ladies" is sweet and strong like a noon Guinness on a Kerryman's gums.

“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.
