Microphone Phelps, Mic Write, Macs the Realest, and, our favorite, Passalacqua will also be performing on Tuesday night. The best part is that this entire night of fun and good music is FREE to you. Instead, they ask that you bring a canned good along to donate to R.A.W.S (Ravers Against World Starvation). It's just another way to give back and be thankful for all that we have. The Grasshopper Underground is located at 22757 Woodward Ave. in Ferndale.
