Those who enjoy the sound of acoustic instruments will enjoy hearing JACK, four hip musicians who make violin, cello and viola sound like nothing you have heard before.

JACK will perform on Sunday, January 27, 3 PM at Laidlaw Performing Arts Center on the campus of University of South Alabama. The concert is part of Mobile Chamber Music's regular season. Tickets will be available at the door.

JACK will also play and talk about the mathematically-inspired music of Iannis Xenakis on Saturday evening, January 26, 7 PM at Satori Coffee House on Old Shell Road. Admission is free, but come early since space is limited. The concert is sponsored by Mobile Chamber Music with help from the Mobile Mathematical Society.

JACK is not an ordinary string quartet. It is a "hyper-modern" ensemble that explores new music and new sounds. They perform around the world and earn rave reviews from music critics of all types. The Washington Post wrote: "The string quartet may be a 250-year-old contraption, but young, brilliant groups like the JACK Quartet are keeping it thrillingly vital."

So unless you hear them, you don't know JACK.

Regular admission to Sunday's concert is $20. Student tickets are only $10. Information is on facebook; www.mobilechambermusic.org, music@mobilechambermusic.org; 251-478-6021.
