WHO’S IN TOWN

Modern-day Renaissance singer-songwriter Jeb Loy Nichols’ creative path has taken him from the Midwest to London and rural Wales (and then to Austin and New York City). His music reminds one of Nick Cave, rooted in punk with a fine, aged softness. Bob Sima opens. 7 p.m. $13.50. Rams Head On Stage, 33 West St., Annapolis. ramsheadonstage.com.
