The singers of Celtic Thunder bring their new high-energy show, "Voyage," to Shea's Performing Arts Center (646 Main St.) at 8 tonight.

The show, backed by the Celtic Thunder orchestra, includes solos, group songs, a bit of dancing and even some comedic moments. Backdrops include such familiar Irish visuals as stone walls, rustic pathways, green mountainsides and the sails of emigrant ships. The songs include a wide range of tunes that will be familiar to local live music fans, from haunting traditional melodies to raucous sing-along favorites, with a few American folk and country favorites thrown in.

The singers, Neil Byrne, Emmet Cahill, George Donaldson, Keith Harkin, Colm Keegan and Ryan Kelly, each play various instruments.

Celtic Thunder was named Billboard's Top World Music Artist in 2009 and has issued eight albums and eight live performance DVDs.

The 63-city tour opens as Harkin, a singer and a songwriter from Derry, had his self-titled debut album issued by Verve Records. The album features original pieces, as well as covers of several tunes, including Van Morrison's "Have I Told You Lately That I Love You," and "The End of the Innocence" by Bruce Hornsby and Don Henley.

Tickets range from $15 to $72 (box office, Ticketmaster). Call (800) 745-3000.
