This episode is the first time we see Lane’s bandmates, Zack and Brian.
Zack is the lead guitarist and vocalist for the group, shown almost immediately to be a typical frontman, good looking and confident. He later becomes Lane’s boyfriend, then husband. Zack is played by Todd Lowe, who at this stage had had small roles in a few films, such as Where the Heart Is, and The Princess Diaries, and appeared in two episodes of Walker, Texas Ranger (once as a character named Zack!). Amy Sherman-Palladino used him again later in Bunheads, and he became best known for his role on vampire drama True Blood.
Brian is the bassist for the group, a little awkward and nerdy. He is played by John Carbrera, who is a friend of Sean Gunn who plays Kirk on Gilmore Girls; they attended the same theatre school in Chicago. At this stage Carbrera had had a few minor roles in TV shows such as CSI and NCIS. The previous year, he had won an award for his work in theatre. Recently, he has increasingly concentrated on screenwriting.
There have already been characters with these names on Gilmore Girls – Zach was Lorelai’s classmate at community college in Season 2, and Brian was one of the waiters at the Independence Inn in Season 1.
