Top producer Tao begins working with Angela, who's yearned for a music career. Carole and Tuesday sneak into a concert hall to practice their song.

Gus somehow gets Carole and Tuesday a gig on the main stage at a huge festival. The catch: they're a standby act for the famous, difficult Joshua.

The duo make the cut for Mars Brightest, along with Angela and a Tuesday mega-fan named Cybelle. Now they just have to perform their very best!

The Mars Brightest semifinals begin with Ertegun as guest judge. Tao tells Angela to change her song, and Cybelle's visit raises Carole's suspicions.

It seems like all is lost, but Gus encourages Carole not to give up. With time running out before the final, they launch a rescue operation.

Going indie means finding people themselves. Gus persuades the legendary and very strange Tobe to work with the duo. Angela enters the studio.

The single charts, and Gus decides they'll play South by Southwest. On the way home from rehearsal one night they meet Carole's childhood idol, Flora.

Carole and Tuesday start rehearsing for their performance as Mars Grammy nominees. Tao runs afoul of the law just as Angela's replica is completed.

After Skip gets arrested, the duo and their industry colleagues decide to create a supergroup song opposing Valerie's policies. Tao is still at large.
