My goodness, 2015 is a great year for hip hop. We’re only halfway through the year, but considering the benchmark releases by Kendrick Lamar, Action Bronson, and Death Grips, the bar of modern rap keeps rising by orders of magnitude. Some say the best music has already dropped, but the year is still young.

Donnie Trumpet and the Social Experiment came out of nowhere with Surf, an LP that rumbled the eardrums of music fans nationwide. After selling 600,000 digital copies on iTunes, the Social Experiment proved that their hip hop prowess deserves a place on every critic’s best-of lists at the end of the year. But, even when the year is over, listeners will still have the infectious grooves from Surf reverberating in their brains.

The track “Slip Slide” stands out as a necessary cut. Overtop percussion and brass reminiscent of Buddy Rich’s jazz band, rap legend Busta Rhymes spits verses in his trademark baritone cadence; subsequently, the door opens for Janelle Monae and B.o.B. to take up the vocal reins, adding soulfully smooth facets to the groovy track. The names on the song are household fixtures, but each vocal track would fall slightly short of perfect without the superb instrumental heroics from Donnie Trumpet and his Social Experiment band.

Don’t sleep on this album. Yes, “Slip Slide” is a great cut from the album, but Surf stands out as a contender for hip hop album of the year.

So, what are you waiting for?
