Remember Kriss Kross? Those two-hit wonders who wore all their clothes backwards and wanted to "warm it up" and "make you jump, jump" in 1992? Get ready to meet 2015's version.
Rae Sremmurd come complete with an absurd name (it's "ear drummers" spelt backwards), confusing back story (are they teens or dudes in their 30s?) and some seriously stupid songs.
"Unlock the swag, the swag unlocked" is one of their hooks, chanted so slowly and repeated so often you can barely call it an actual song.
It's a trick rapping brothers Swae Lee (he's 19) and Slim Jimmy (22) use often and, when paired with surprisingly current bass tricks, they can conjure up some heat.
