Deck the halls!

Join soul rockers Train, a cappella aficionados Pentatonix and singer songwriter Andy Grammer for an extra special holiday celebration at the Microsoft Theater this December!

The multi-platinum chart-toppers from San Francisco Train have been rocking the radio waves with their country, soul and blues-infused roots rock since 1993. Expect some songs from latest (and seventh!) studio album, Bulletproof Picasso plus the hits you already know and love like Drive-By, Hey Soul Sister and, of course, the anthemic Drops of Jupiter.

Alongside them are Pentatonix, who are riding the massive a Capella resurgence (Pitch Perfect, anyone?) A five-piece who found success through NBC's The Sing-Off. The group put their own meticulously in-tune spin on everything from Katy Perry to Marvin Gaye, with a Daft Punk mash-up/medley quickly becoming their signature number. After extensive 2015 tour, they'll be bringing their best, and hopefully a whole lot of material from their record-breaking festive record 'That's Christmas to Me.'

Finally, blue-eyed soulster Andy Grammer rounds out this exciting line-up. From busking on the boardwalk to the Billboard Hot 100, Andy is a chip off the old block of bands like Coldplay, The Fray and One Republic.
