Two performances in the coming days put rock classics front and center in a large-scale theater setting. Thursday night brings The Machine, the No. 1 Pink Floyd touring show in the country, to the stage of the Collins Center for the Arts. Playing the big hits and lesser-known cuts from Floyd’s 16-album career, The Machine combines excellent musicianship with a stellar light and video show. The performance is at 8 p.m. April 29, and tickets are $10 for University of Maine students, $27 for the general public, available by calling 800-622-TIXX. On Sunday, the Camden Opera House welcomes Barrage, a troupe of 12 fiddlers backed by a rock band, in a performance at 2:30 p.m. May 2. Barrage combines jazz, classical and rock with dance and an impeccable stage show, described as “Riverdance” meets “Stomp” and a “high-octane fiddle fest.” Tickets are $25, or $8 for those under 18, and prime seating for $40. They are available by visiting www.baychamberconcerts.org.
Elwood Dowd may be a character dreamed up in the 1940s by playwright Mary Chase, but nearly 70 years on, he’s still an instantly recognizable fellow — at least, when he’s in the company of his 6-foot-3-inch imaginary rabbit companion, Harvey. The Belfast Maskers will present their take on the 1944 Pulitzer Prize-winning play “Harvey,” beginning with a preview performance at 7 tonight, April 29. Is Elwood crazy? Or is he just living in his own happily bizarre little world, hurting no one except those unable to relax and accept him? Like, for example, his high-society sister, Veta, who tries to have him committed to an insane asylum. The Maskers show is directed by Angela Bonacasa, who made her directorial debut with the company with last fall’s production of Agatha Christie’s “The Mousetrap.” Performances are this weekend and next, at 7 p.m. Fridays and Saturdays and 2 p.m. Sundays at the Maskers Waterfront Theater on Front Street in downtown Belfast. Tickets are $15 for adults, $10 for teens, with Thursday’s preview performance $8.
