The giant Super Bowl episode of "Glee" is still days away -- but we've got video of two of the songs right now!

Darren Criss continues his streak of fantastic performances on the show this Sunday with a stellar, a cappella rendition of Destiny's Child's "Bills, Bills, Bills" with the rest of The Warblers -- including Chris Colfer's Kurt.

Lea Michele's Rachel switches up duet partners in the episode, ditching Finn for Mark Salling's Puck -- who accompanies her on Lady Antebellum's "Need You Now."

Check out the two performances above -- and click here for a listen at the killer mashup of Michael Jackson's "Thriller" and Yeah Yeah Yeahs "Heads Will Roll."

The episode airs immediately following the Super Bowl this Sunday.
