The Mentalists are a London girl group who have covered one of my favorite songs from last winter, "Kids" by MGMT, using their iPhones and iPods running apps they downloaded from the iPhone app store.
If you're unfamiliar with MGMT's "Kids," I've included it below. The Mentalists' http://www.trendhunter.com/submit-newcover is pretty solid. The ladies used DigiDrummer Lite, miniSynth, Retro Synth, and Ocarina for their cover. Again, I'm biased because I already like the song, but compare The Mentalists' version above to the original MGMT track below and tell me what you think in the comments!
