The Miami-based rap group ¡Mayday! has taken to The Black Keys album Brothers, and recorded an awesome freestyle over "Sinister Kids". With a funky and up paced beat, these artists go in and make a name for themselves. ¡Mayday! has been featured on Tech N9ne's latest Collabos album and provided great support, and they stick to the solo grind on this freestyle, and create a great track. Check the "Sinister Kids Freestyle" out and enjoy.
