In celebration of their new sonic brand identity, Mastercard has spent Grammy week bringing melody to life—and there’s still some time left for friends of the brand to join the party before the big show tomorrow. From 12 PM to 7PM PST, the Mastercard Sensory Lab at Fred Segal will be open to visitors for one last day, where invited attendees will get to hear the brand’s new transaction sound for the first time.

“What I love most about the Mastercard melody, is just how flexible and adaptable it is across genres and cultures,” said Linkin Park singer-songwriter Mike Shinoda. “It’s great to see a big brand expressing themselves through music to strengthen their connection with people.”

In addition to previewing the new melody tying all of Mastercard’s physical, digital and voice environments together, visitors will have the opportunity to buy some exclusive Joefreshgoods and Superduperkyle merchandise (limited to Mastercard holders only).

Check out some shots of the first day of the experience below, and follow @Mastercard on all socials for a look at who’ll be stopping by the lab today.
