All week the Blue Point Brewery has been hinting at a huge surprise coming to its Patchogue headquarters Friday evening.

Now the secret is out.

The 90s alternative band the Gin Blossoms will be taking the stage behind the brewery at 161 River Avenue for a free pop-up concert.

Leaders at the Greater Patchogue Chamber of Commerce were given the go-ahead at 2 p.m. Friday to publicize the concert.

The show is set to start at 6 p.m.

“I have just been informed that 90’s Alternative Rock Band, The Gin Blossoms will be doing a ‘surprise’ show at Blue Point Brewery at 6 PM tonight!” the chamber’s executive director, David Kennedy, informed area businesspeople via email. “And even better, it is a free performance, no cover charge.”

“If you’re a fan then this a great opportunity for you,” Kennedy wrote. “Or even if you are not, you are sure to recognize there big hits like ‘Hey Jealousy’ and ‘Found Out About You.'”
