Recently, when people ask me who my favorite undiscovered rapper is I always try to put them on to Sidewalk Kal. Currently based out of Chicago, Sidewalk Kal has been blessing us with a consistent stream of great music for a while now and shows no sign of slowing down. “OctoTrex” is Kal’s latest release and it has him teaming up with Brooklynite ID 4 WINDZ. WINDZ provides an understated yet memorable beat for the two to spit over with Kal stepping up his word play and delivery to some of the best we’ve seen from him so far. WINDZ is similarly old school minded rapper with a harder and grittier lyrical bent to compliment Kal’s more abstract musings and references. I also just found out that I went to high school with Kal’s younger sister which is pretty darn cool, amirite?
