This Prague Spring Features Music With a rousing program of local and international music acts, Prague Spring kicks off on Saturday, offering a tantalizing prelude to the Czech capital's packed summer festival season. This year's set list is long and impressive, pulling talent from city orchestras across Europe, including Vienna, St. Petersburg, London, Slovakia, Warsaw and, of course, Prague. Now in its 67th year, the festival will open with the Czech Philharmonic at the Municipal House in the heart of the city's Old Town. Concerts will follow over the next three weeks at various other historic locales around Prague. From the Rudolfinum and St. Agnes Convent along the banks of the Vltava to the lovely Wallenstein Gardens below the Castle grounds and the newly renovated National Technical Museum atop Letna Hill, Prague Spring takes over the city. In addition to heavyweights like the St. Petersburg Philharmonic (May 17) and the BBC Symphony Orchestra (May 20 and21), there will also be smaller groups in the mix, like Accademia Bizantina (May 18), the Gypsy Devils (May 24) and the Dun Huang New World Ensemble (May 31). Round table discussions with orchestra conductors and soloists will follow some performances, according to festival staff. The Prague Spring lineup includes a trio of classical opera performances as well. Dvorak's "Jakobin" (May 14), Stravinksy's "Rake's Progress" (May 22) and Britten's "Gloriana" (May 25) will all play at the National Theater. The festival winds down June 3 with the Prague Symphony Orchestra giving the closing night concert.
