At age 19 three friends and I formed a band called Battletoads on Ice. Hours after our only rehearsal, we played The Muse. Reptar is also a band of high school pals, and they also namedrop childhood nostalgia. Whereas Battletoads was a video game about buff, bipedal, alien frogs dressed like Mad Max, Reptar was a Godzilla-like character favored by the kids of ’90s-era Nickolodeon cartoon Rugrats. Reptar’s indie rock (a less experimental Animal Collective or Dan Deacon; a dancier Cold War Kids) focuses on moving the audience: Like most tracks on their latest EP Oblangle Fizz Y’all, “Context Clues” breaks down mid-song into tame but catchy electronica. And their formula works. Last year Athens, Ga., alt-weekly Flagpole deemed the Athenians “Best Live Band,” and since then the quartet has supported Phantogram, Cults and Foster the People.
