So This Happened: 'Baby Got Back' Got Backed-Up By An Orchestra

Now THIS is a mash-up.

Congratulations, Seattle Symphony, because you just pulled off one of the coolest, most unexpected things we've seen of late. The classically trained musicians teamed up with hometown boy Sir Mix-A-Lot to bring us the fanciest version of "Baby Got Back" that we've ever heard.

"What I want to do now is something you really should not do," the rapper proclaimed before recruiting a bunch of ladies to come onstage. As soon as composer Gabriel Prokofiev's arrangement of the '90s anthem kicked in, though, folks were 100 percent on board.

"Tonight is Orchestral Movements From The Hood Night," Mix stated, explaining the core of the evening's festivities: Seattle Symphony's Sonic Evolution. It's a project that bridges the gap "between the Symphony and Seattle's storied reputation as launching pad for some of the most creative musicians on the popular music scene." None more creative than this, no doubt.

Even classical musicians don't want none unless you've got buns, hun. Huh. Who knew?
