Well, that escalated quickly. I mean, that really got out of hand. Angel Haze and Azealia Banks, two very good rappers who seem to have a lot in common, started out today by going at each other’s necks on Twitter. (Read the whole exchange here.) And already Angel Haze has fired off the first on-wax attack, delivering the double-time bloodthirsty dis track “On The Edge.” If nothing else, it shows that Angel Haze is an absolutely ridiculous monster of a rapper. I do not expect Azealia to let this one slide, so look for this to continue. In the meantime, download “On The Edge” below.
