Glee returns tonight at 9/8c on Fox with an all new episode featuring the debut of Adam Lambert and music from the catalogs of Lady Gaga and Katy Perry!

After a very emotional previous episode which featured the characters of Glee mourning the death of Finn Hudson, Glee will return to some sort of normalcy tonight with “A Katy or a Gaga.” Here’s what show runner Ryan Murphy had to say about what we can expect from Glee season 5, episode 4:

New Directions in Lima and the characters in New York explore “who they are as artists,” using the music of Katy Perry and Lady Gaga in the process.

Check out a preview of tonight’s episode which features Adam Lambert’s new character Elliot “Starchild” Gilbert as well as the return of Demi Lovato’s character Dani:

You can listen to all of these Glee songs in our previous story.

The songs we can expect to hear from Lady Gaga’s catalog on tonight’s episode are “Marry The Night” performed by Adam Lambert’s “Starchild” character as well as “Applause” performed by members of New Directions. The Katy Perry songs that we can expect on tonight’s episode are “Wide Awake” performed by Jake, Kitty, Tina and Unique as well as “Roar” performed by Dani and Starchild.

Glee fans were brought back to life about the series this week when a rumor surfaced that Ryan Murphy will be developing a Glee spinoff series revolving around Lea Michele and others on the cast. Nothing about this spinoff has been confirmed by Murphy or Fox thus far.
