The a cappella mixologists of Straight No Chaser sing like their name implies: no backing bands, no synthesizers, just 10 skilled vocalists sharing their music and sense of humor. Straight No Chaser will shake up traditional tunes and new music from artists like Cee Lo Green and Lady Gaga this Thursday at the Palace Theatre.

The a cappella mixologists of Straight No Chaser sing like their name implies: no backing bands, no synthesizers, just 10 skilled vocalists sharing their music and sense of humor. Straight No Chaser will shake up traditional tunes and new music from artists like Cee Lo Green and Lady Gaga this Thursday at the Palace Theatre.

Straight No Chaser formed in 1996 when the original members were students at Indiana University, and since then a video of the group performing its humorous mash-up "The 12 Days of Christmas" has been viewed more than 13 million times on YouTube. The video's blend of holiday hits and Toto's "Africa" gained the attention of Atlantic Records in 2007. Since then, 10 alumni from the original Straight No Chaser group have released three full-length albums, while a rotating group of IU students continues to perform at the university under the same name.

Original group member Charlie Mechling said the singers want people to hear music in a different way than they're used to.

One of their recent songs mixes "Somewhere Over the Rainbow" and Jason Mraz's "I'm Yours." "Those songs are 50 years apart, but they go together well because they're good songs," he explained. "If you find a song that's a good quality song, it doesn't really matter when it was written; it's just 10 voices singing."

Member Don Nottingham said a cappella music is resurging in popularity, thanks in part to music from TV shows like "The Sing-Off" and "Glee."

"I think people can really appreciate that you're just getting a human voice and it's a really pure form of music, as opposed to so much stuff that's out there that may be really processed or may be over-synthesized," he said.

Nottingham said the intimacy of a cappella helps the vocalists of Straight No Chaser connect with their audience.

"You're always going to have a good time, you're always going to get some laughs - usually at our expense," he said.

Though the 10 college friends are now seasoned, signed artists, Mechling said their mentality hasn't changed.

"We get up on stage and have fun and sing the songs that we want to sing. We don't put much more thought into it than that, other than having fun and the audience having fun," he said.
