Shaggy

Mr. Smalls Theatre

400 Lincoln Ave., Millvale

Time: 8 p.m.

Admission: $20

Believe it or not, Shaggy has released four albums in the last four years. The reggae fusion singer hasn’t scored a hit like “Angel” or “It Wasn’t Me” on any of those LPs, but both of those songs still are played in college dorms across the country (“It Wasn’t Me” has almost 25 million plays on Spotify alone). This tour marks his second leg supporting 2013’s Out of Many, One Music.
