Conspirator, the Disco Biscuits offshoot featuring Marc Brownstein and Aron Magner, will play a Rocks Off cruise this summer. The livetronica outfit will perform as Conspirator aboard the Temptress on August 16. The two musicians are a natural fit for Rocks Off’s 10th Anniversary Concert Cruise series, having played the New York-based promoter’s various ships in different configurations over the years. The boat will depart from 41st St in Manhattan at 8 PM.
