Roby Lakatos is a Romani (Gypsy) violinist from Hungary. The Romani or Gypsy sound fascinated 19th-century composers like Liszt and Brahms. Lakotas enchants with that sublimely romantic classical music seamlessly blended with jazz, pop, Broadway and film scores into one sweeping, dramatic, hyper-kinetic Gypsy rave. Lakatos is technically amazing in blazingly fast solos and slow sections of notes that sustain to reach the deepest recesses of the hall. (Student tickets cost $15.)
