Heads up hockey fans, the Philadelphia Flyers have announced two special themed nights dedicated to rock icons the Grateful Dead and Pearl Jam.

Later this month, the Flyers will host a celebration of each band at two back-to-back home games at Philly’s Wells Fargo Center with renowned cover bands and one-of-a-kind co-branded T-shirts featuring Flyers mascot Gritty embedded in each band’s iconography.

First, on Tuesday, March 12th, the Flyers will hold the team’s third annual Grateful Dead Night as they take on the San Jose Sharks. Every ticket purchased through this special ticket package link will come with a commemorative Flyers x Grateful Dead T-shirt and entrance to a pregame concert by Splintered Sunlight beginning at 5 p.m.

Then, on Thursday, March 14th, the Flyers will honor Pearl Jam, who played one of its most iconic shows, the “Ten Show,” on April 29th, 2016 at Wells Fargo Center and will return to the venue for two shows this September. Every ticket purchased through this special ticket package link includes a commemorative Flyers x Pearl Jam T-shirt and access to the pregame tribute band performance by the Ledbetters. A portion of the ticket proceeds will support Pearl Jam’s Vitalogy Foundation, and all fans in attendance will have the chance to take a photo with the banners celebrating Pearl Jam’s ten sold-out shows in South Philadelphia located on the Main Concourse.
