‘Seven Brides for Seven Brothers’ is rowdy fun

“Seven Brides for Seven Brothers,” now onstage at Riverside Center for the Performing Arts, is a boisterous battle of the sexes as it explores love and relationships in the Oregon frontier during the 1850s. A delightful throwback to the golden age of musical theater, this feel-good production just sings in the hands of director and choreographer Penny Ayn Maas.
