Critically-acclaimed trio Pistol Annies and folk-country duo Civil Wars have collaborated with traditional Irish band the Chieftains on 'Voice of Ages,' a new album to commemorate the group's 50th anniversary.

The disc, which is set for release on Feb. 21, features a new tune written and recorded by the Civil Wars (Joy Williams and John Paul White) called 'Lily Love,' which was co-produced by T Bone Burnett and the Chieftains' Paddy Moloney.

"What a treat to have such wonderful artists in Joy and John Paul and to have them write a song to celebrate the Chieftains' 50th anniversary album," Paddy Moloney tells Rolling Stone. "I couldn't be more pleased. In the 'Lily Love' melody, I can hear strains of the Irishness of it, and to play, arrange and add my thoughts to it just came naturally."

'Voice of Ages' also will feature the Decemberists, Punch Brothers, Bon Iver, Secret Sisters and more. Rolling Stone is currently featuring an exclusive stream of 'Lily Love' on its site.
