For those of you familiar with Single Cell Productions, you know the themed bondage/fetish events known as Purgatory. Soon they will come to an end (the last one, titled Ragnarok, will go down at Amos' Southend on April 18), as all good things must. Welcome, ever so precautiously: SCP's new dance party, Hazmat, which features three DJs, including DJ End, DJ Onesiktrik and DJ Koji spinning harsh and heavy industrial music. Check it out when it goes down on Fri., March 27 at The G & G Club. 18 and up. For more information, visit www.singlecell.us. $12-$15. 8 p.m. The Garden & Gun Club, 820 Hamilton St. 704-246-1752. www.thegandgclub.com.
