Concert in a Can is the 19th episode of Season 1 of Lab Rats. It's the 19th overall, and aired on October 29, 2012 on Disney XD.


Marcus, the new kid at school, forms a band with Adam and Chase. However, Leo's suspicious towards Marcus, and keeps on questioning him. At the house, while Adam and Chase are out of the living room, Marus smashes his guitar and puts it into Leo's hands, blaming him for it. At the school, before the guys play the Concert in the Can, Leo brings along a tablet with Eddy on it, who video taped the scene. Just as Leo's about to bust him, Marcus confesses, but rather than apologizes to Leo, he threatens him, awakening Leo's all-due suspicion and hatred for Marcus.


Meanwhile, Bree tries to do a father-daghter project with Mr. Davenport, who ends up helping the boys (Marcus, Adam and Chase). In the end, he makes it up to Bree by them playing in the Concert in the Can invention together.
