On this edition of ST, we're talking about two noteworthy cultural events happening in downtown Tulsa this weekend. First off, we discuss the final concert of the Tulsa Symphony Orchestra's current season, "Inside Out!," which happens tomorrow night (Saturday the 12th) at 7:30pm at the Tulsa PAC. We speak with Kari Caldwell, the principal cellist and board president of the TSO, who'll be the featured soloist as the symphony performs "Don Quixote" by Strauss. This concert will also feature Jennifer Higdon's "Blue Cathedral" and Haydn's "Symphony No. 88" --- and Gerhardt Zimmermann will be the Guest Conductor. Moreover, as Caldwell tells us --- in an exciting "first" that ones hopes the TSO will continue from time to time --- this concert will also be offered in a free-to-the-public simulcast at the Guthrie Green (at 111 East Brady Street). Also on our program, we visit with dancer and choreographer Jennifer Alden, the co-founder and co-artistic director of the Tulsa-based Portico Dans Theatre. Alden is also one of the organizers and key participants in the upcoming eMerge Dance Festival, which will also happen tomorrow night, and which is entitled "Submerged: Moving in the Tulsa Tunnels." This event begins at 7pm, and it's being presented by Living Arts of Tulsa (where Alden chairs the New Dance Committee). Tunnels beneath downtown Tulsa, you ask? Really? Where? Alden brings us up to speed on this matter --- and talks about the various dancers and dance companies one can see performing in this lesser-known space tomorrow night.
