Romania's most famous export is probably vampire stories, but this Eastern European outpost also has an intense musical heritage, personified by the great 20th century composer George Enescu (not to mention his protegé, the radiant pianist Dinu Lipatti). Like most Romanian musicians, and even many beyond its borders, Enescu was deeply inspired by the lively and soulful folk music of his country. This weekend, Orchestra 2001 celebrates that legacy with a pair of concerts titled Rhapsody Romaniana. Enescu will be represented by the American premiere of his final work, "Chamber Symphony," written in 1954, when the composer, exhausted and impoverished, was living in exile in Paris, estranged from the Communists then in control of his homeland. The work has only recently been reassembled from parts discovered by Romanian-born cellist George Atanasiu (who has performed with Orchestra 2001 in the past). Artistic director James Freeman will also conduct Romanian-themed music by Bartkhis "Romanian Folk Dances"and new music by Liviu Marinescu, Brian Kershner, and yes, a vampire number, "Lucy and the Count," by double bassist Jon Deak, who will also take the solo role as Count You-Know-Who.
