Alt-rock band Guster, who for the past 25 years have been one of the most popular bands to hail from New England, and whose co-lead guitarist and singer Adam Gardner has lived in Portland for nearly 15 years, will play a series of unique shows over the course of an August weekend this weekend.

The “Guster on the Ocean” experience begins on Friday, Aug. 11, aboard the Casco Bay Ferry, which will cruise around the bay, and will feature Guster playing a concert for 200 fans of the band.

Then, on Aug. 12, the band will play a full concert at Thompson’s Point in Portland, with local guests the Ghost of Paul Revere, Spencer Albee and the Maine Youth Rock Orchestra. Tickets for this Saturday concert are all $40 and go on sale via Ticketmaster at 10 a.m. Wednesday, May 3.

Finally, the weekend wraps up on Sunday, Aug. 13, with a kayaking trip from the Portland waterfront to a secluded location on the Casco Bay, where Guster will perform an intimate acoustic set.

While tickets for the Aug. 12 concert are available for the general public, tickets for the boat cruise and kayak expedition will only be available to people that have already bought tickets for that Aug. 12 concert by Friday, June 30. Those ticketholders will be able to enter a lottery to purchase tickets to the Friday and Sunday expeditions. More information will be available online at statetheatreportland.com.
