If you think Peter Klaven and Sydney Fife are the biggest Rush fans in the world, you're sadly mistaken.

On Wednesday's episode of The Goldbergs (8:30/7:30c, ABC), Johnny Atkins (Sean Marquette) introduces Erica (Hayley Orrantia) to the prog-rock stylings of Rush ("Tom Sawyer," natch), and it's love at first sight — in more ways than one.

Check out the exclusive sneak peek above to see Erica morph into a "rock 'n' roll butterfly."

The Goldbergs airs Wednesdays at 8:30/7:30c on ABC.
