As predicted, tomorrow’s Hot 97 ‘Who’s Next’ July showcase with Mike Posner and Big Sean is officially sold out.  Why?  Besides having two of the summer’s biggest buzz artists headlining the bill the recent additions to the night are solid too.  Odyssee, Kev Brown, Kenn Starr, & Kaimbr are The Low Budget Allstars and have been confirmed for the night as well as Homeboy Sandman.  The Low Budget Allstars should be familiar to NY underground heads from the track off of Marco Polo’s Port Authority.  Besides the collab on the track, many of these guys go way back not forgetting Kev Brown and Kenn Starr from the ‘Walk the Walk’ mixtape days.
