As options for summer theater proliferate, the hard line that once separated one theater season from the next has more or less disintegrated. As part of this explosion of summer productions, MusicalFare Theatre (4380 Main St., Amherst) has announced four August shows for its newly constructed Premier Center Cabaret. The slick performance space, complete with a full bar, cocktail tables and chairs and a raised stage against a wall of tinted glass, has been broken in with a series of cabaret performances and mini-musicals and is now ready for its close-up. First up is “A Tuff Shuffle: Backstage with Louis Armstrong,” a one-man show starring Western New York native Danny Mullen as the famous New Orleans-born trumpeter, at 8 p.m. Friday. Next is a return engagement of “A Gershwin Celebration” featuring pianists Randall Kramer and Theresa Quinn playing the hits of George and Ira Gershwin, at 4 and 8 p.m. Saturday. On Aug. 24, harpist Rita Costanzi, formerly of the Vancouver Symphony Orchestra and the CBC Radio Orchestra, will give a performance of her one-woman biographical show “A Score to Settle.” And from Aug. 29 to 31, the space will host the return of the popular “Say Hello! A Musical Parody of Scarface” created by local director Chris Kelly and a team of actors and musicians. Tickets for “A Gershwin Celebration” are $20; the others cost $15 each.
