Flying united

Reggae-rock act 311, alt-pop band Fiction Plane, and rap icon Snoop Dogg wouldn't seem to have much in common, but seeing as they are in the thick of a shared summer tour, their fan bases must overlap. Tonight, as part of the Unity Tour, you can see Dogg, 311, and Fiction Plane (which is heavily influenced by the Police, not surprising since the group is fronted by Sting's son Joe Sumner) at the Comcast Center. 311 is all about unity - and variety. On its Unity tour last year, the band played with Matisyahu and the English Beat. 6:30 p.m. $27.50-$37.50. Comcast Center, 885 S. Main St., Mansfield. 508-339-2333. ticketmaster.com
