The Machine presents a surgically accurate interpretation of the music of experimental rock legends Pink Floyd. The group has been hailed as the cream of the cover-band crop because of their faithful replication of the Pink Floyd experience, complete with psychedelic lighting and improvisation, drawing from Pink Floyd's many albums throughout the group's three-decade career. Gathering widespread attention and playing some of the biggest gigs in the world -- Bonnaroo amongs many others The Machine has perhaps inspired more than one flashback. The Machine promises to re-create the monumental sounds of Pink Floyd at The National Saturday, March 29, at 8 p.m. $15-$18. Call 612-1900 or visit www.thenationalva.com.
