Singer, songwriter, producer, educator, and YouTube star Peter Hollens has applied his considerable a cappella chops to a host of different styles, including jazz, film, and video game music, Christmas songs, and pop. With the aptly named Legendary Folk Songs, Hollens takes on 14 classic English, Irish, and American folk tunes, including "Danny Boy," "Greensleeves," and "Shenandoah." The LP features guest spots from David Archuleta, Anna Gilbert, the Swingles, Home Free, and the Hound + The Fox. ~ James Christopher Monger
