The St. Louis Post-Dispatch called it the most beautiful music on the planet and it seems they're not the only ones who feel this way.

When publications review Le Mystere Des Voix Bulgares (The Mystery of the Bulgarian Voices), words like "wonderful," "unforgettable" and "breathless" are often emphatically used.

The 26-member, all-female a capella ensemble is a Grammy Award-winning traditional Bulgarian folk choir. The group is touring the U.S. this winter with a special program that includes traditional favorites, fresh repertoire and holiday songs, and performs at the Pabst Theater on Friday, Jan. 18.

Tickets are $29. 50 and go on sale Friday, Nov. 16 at 12 p.m. at the Pabst Theater box office, on the web at www.pabsttheater.org and www.tickets.com, or by calling (414) 286-3663 or (800) 511-1552.
