What is the name of the band that plays at Lane and Zack's wedding?

Hep Alien is the band that plays at Lane and Zack's wedding.

Hep Alien is Lane Kim's rock band, formed with Zack Van Gerbig, Brian Fuller, and Gil. Lane plays drums, while Zack serves as guitarist and vocalist. The band performs at local events and rehearses while its members try to balance music with work and relationships.

Lane and Zack eventually marry in a two-part ceremony that combines a traditional Korean celebration with a more informal American-style party. Hep Alien provides the music for the wedding festivities.
