Alternatively Children of the Night consists of Energy singer Tank, and High Fives mastermind Mike Rendini's Acoustic/Doo-Wop influenced/Horror Punk Project:

Formed in the Fall of 2004, Children Of The Night from southeastern Massachusetts began by doing complex renditions of Misfits songs. Just recently the two have graduated to putting together original material containing the same morbid feel crossed with the catchiness of 50s Doo-Wop and early 60's rock n roll. Mike Rendini is responsible for the bulk of the composing and producing, while Jason Tankerly adds his unique vocals to the mix. The duo is slated to release a Misfits tribute album, on Rock Vegas Records, full of their interpretations of the legendary punk rock hits.
