Haitian-American musician Daniel Bernard Roumain uses his knowledge of classical music to whip up a concoction of sounds with rock, soul, electronica and other genres. His long hair just doesn't seem to get in the way of his playing the violin. Check out this composer when he visits McGlohon Theatre to perform selected solo and duet works from his most recent album etudes4violin&electronix. Tickets start at $19. 8 p.m. McGlohon Theatre, 345 N. College St. 704-372-1000. www.blumenthalcenter.org.
