Halloween on Massachusetts Street may hold the rank of the craziest free-for-all party in Lawrence each year. Last Halloween was the first installment of Nightmare on Mass Street, a KRBZ 96.5 (the Buzz) and DJ C-Vaughn presentation that drew many Kansas Citians westward down Kansas Highway 10. For Nightmare II, expect 50,000 watts of sound, an assortment of fog and lighting mechanisms, and a sluttiest-costume contest worth $200 that will surely draw once-a-year-hookers from all corners. Sonically, breaks will be the dominant force. Vizual Gym, Ryan Espy and DJ Looe are set to spin nu-skool breaks and electro, with DJ Chief (of Lincoln, Nebraska), C-Vaughn and DJ Fixx (Buffalo, New York) handling Florida breaks and nu-funk. It's 18 and older and rages until 3 a.m. or until the sluts come home.
