Mark your calendars for the return of both Primus and Mastodon to Portland, Maine as they rock the Maine State Pier on Sunday, May 27th! Waterfront Concerts announced that the pair would be co-headlining a show during the holiday weekend on Portland's waterfront.

Both Primus and Mastodon are no strangers to Portland. Primus took the Maine State Pier stage last July, and Mastodon played Portland last May. Now both bands will be back with headlining sets for what should be a very loud Memorial Day weekend.
