Apples In Stereo!
These guys are one of my current faves! Hooky guitars, catchy rhythms, moog organ, and crazy lyrics are right up my alley! I always thought they sounded like a mixture of the Ramones, Archies, and The Beach Boys. There's some definite Brian Wilson influences in the musical arrangement. I could imagine their music would fit in perfect with Scooby Doo!
The great thing about AIS is, they're still a band! They play Bubblegum that's fit for the 2000's. I know we definitely need more music like this.
Here's one of their videos, and it's directed by Elijah Wood (I heard that he's a big fan). Enjoy!
