After recruiting drummer Ernie Kim, the band recorded their eponymous debut album over a weekend in the DeGeorge family living room.
Released in June 2003 under the Eskimo Laboratories record label, the album contains six of the seven songs composed on June 22, 2002, and another twelve written spontaneously and immediately thereafter recorded.
 In "the summer of" 2003, Harry and the Potters set out on an American tour, performing at libraries.
The fifth Harry Potter book – Harry Potter and the Order of the Phoenix – came out that summer and on June 21, 2003, the highly anticipated day of release, the band played five sets in a span of 24 hours.
The library gigs drew crowds of mostly children and their parents.
The brothers played a show at the library in Dorchester, Massachusetts, that August where they noticed the children in the audience singing along.
Joe said, "Paul forgot the words to one of the songs. [
The kids] were like, 'You sang it wrong!'"
Paul said, "They'd be like, 'Hey, why'd you skip that song?'
because they knew the exact sequence of the album."
The DeGeorge brothers quickly developed an on-stage persona of dressing in the fashion of wizard-school Hogwarts: white shirts under gray crew-neck sweaters, red-and-yellow striped ties, wire-rim glasses.
In a show of quirky egalitarianism, both brothers play the role of Harry Potter and dress almost identically; Paul is older and to conform to the character’s persona, he is Harry of Year 7; while Joe is the Harry of Year 4.

During May and June 2004, the band worked on their next album, Voldemort Can't Stop the Rock!
in the DeGeorge family shed.
Following the release, the band toured heavily.
The two brothers drove 13,000 miles across the U.S. and into Canada in their "Potter Mobile", a silver 1998 Ford Windstar minivan with a black lightning bolt emblazoned on its hood.
In live concerts, Paul and Joe used pre-recorded backing tracks for much of the tour, but during the second half, Joe called on his childhood friend and former bandmate Andrew MacLeay to join the band temporarily as drummer.

tour, Paul and Joe DeGeorge received a letter from Warner Brothers that stated that the brothers were breaking copyright laws.
Although Paul sent a letter to Warner Brothers in an attempt to smooth things over, Marc Brandon, the company representative, asked to speak to Paul personally.
The two later settled upon a Gentlemen's agreement that, in essence, would allow Harry and the Potters to continue to sell music online and tour, but all other merchandise could only be sold at live shows.
