Unity College Centre for the Performing Arts, 42 Depot St., will present Trì Thursday, April 15 at 7:30 p.m.; and Hot Day at the Zoo Friday, April 16 at 8:30 p.m. Tickets are $10 for Trì, $6.50 for Hot Day at the Zoo.

Emerging Celtic music ensemble Trì features three of New England’s most sought after traditional Celtic musicians. The trio consists of award -inning bagpiper Matthew Phelps; highly acclaimed fiddler Doug Lamey; and the band’s emcee and guitarist Cliff McGann. Pronounced “tree,” the band’s name is translated from the number “three” in ancient Scots Gaelic.

Hot Day at the Zoo, a fiercely progressive four-piece string band grown in Lowell, Mass., is quickly spreading their eclectic roots up and down the eastern seaboard and as far west as Colorado. Fans describe the pioneering sound of David Cleaves (mandolin, vocals), Jon Cumming (banjo, dobro, vocals), Michael Dion (guitar, harmonica, vocals) and Jed Rosen (upright bass, vocals) as ZooGrass. Their bluesy, grassy, jazzy, old-timey, reggae, Americana infused rock ‘n’ roll is inspired by many great musicians spanning a broad spectrum of time and genre, and sights and sounds from the everyday to the exotic are infused in their craft.
