‘Mostly Motown’ Concert at East Hampton Library

The East Hampton Library will be the site of “Mostly Motown,” a concert by Rhonda Denet, a soul-jazz vocalist based in Jersey City, on Saturday at 1 p.m. While Ms. Denet’s repertoire covers everything from the Great American Songbook to Top 40 radio, Saturday’s performance will focus on R&B and soul from the 1960s and 1970s, when the primarily African-American genre crossed over to mainstream audiences.
