This weekend the Florida Orchestra plays Richard Strauss' powerful tone poem Also Sprach Zarathustra — perhaps better known as the theme from Stanley Kubrick's 2001: A Space Odyssey (1968). You're probably overly familiar with at least the first minute and a half — the impressive, epic "Sunrise" movement — but the whole piece is roughly 30 minutes. A little trivia to make you look smart (or nerdy) to your date: The 1896 piece is inspired by the book by Friedrich Nietzsche and translates Thus Spake Zarathustra. And that's only part of the program. Mozart's dramatic Piano Concerto No. 20 will be played by Orli Shaham, who is not your typical pianist. She is also a noted radio host, and among her credits are National Public Radio's Performance Today, the public radio series America's Music Festivals and "Dial-a-Musician," in which she directs listeners' questions about classical music to fellow musicians by dialing them up for the answer. She also is the founder and host of the classical concert series, Baby Got Bach, to introduce preschoolers to music. Guest conductor is Michael Francis, who is British. Concerts are 8 p.m. Friday at the Straz Center for the Performing Arts in Tampa, 8 p.m. Saturday at the Mahaffey Theater in St. Petersburg and 7:30 p.m. Sunday at Ruth Eckerd Hall in Clearwater. $15-$45.
