Flosstradamus are a DJ/Producer duo from Chicago whose tracks come in a variety of musical styles. The Major Lazer remix displayed above is a prime example of the little known genre Trap, a variant of Dirty South rap music. They've had some big releases recently on labels such as Mad Decent and Fool's Gold, and have collaborated with big names like Diplo on tracks such as this remix of Usher's "Climax", another fine example of Trap music. You should also give this Ludacris remix a listen.
As well as big remixes, they have some astounding originals such as MOTA, a track from their recent Total Recall EP.
Another good example of Trap would be this sick Gotye remix.
