A piano concert in an underground cavern? That is what's planned for Saturday at Longhorn Caverns State Park, when local pianist Joe Cordi will offer a jazz concert as part of the Simple Sounds Cavern Concert Series.

Cordi -- a composer, jazz pianist, guitarist, accordionist and singer -- lives in Austin and will release his new album, "When the Pianoman Plays the Blues," in conjunction with the cavern performance.

Tickets are $17 for adults and $16 for those ages 13 to 19.

Tickets for a dinner held prior to the performance are $27 for adults and $26 for seniors and teens.

No one under 13 will be admitted.
