kiss

They've gone from makeup to unmasked, hard rock to prog, and been one of the world's biggest rock bands for several decades, releasing a slew of classic studio and live LPs along the way.

They've been a fixture on the charts for decades, many current and former members have written memoirs and band co-founder Gene Simmons even had his own reality show, so how much of the Kiss story could really be left untold?

Maybe you had a cool homecoming dance. But you were never Kiss-played-my-homecoming-dance cool.

Kiss take off their makeup and throw a Hail Mary on Sept. 18, 1983 with 'Lick It Up.'

To their loyal fans' horror, Kiss went even deeper into the pop world for their eighth studio album, 1980's 'Unmasked.'

The members of Kiss played their first official concert without their signature makeup in 1983, but they took the stage together au naturel years before that — at guitarist Ace Frehley's wedding in 1976.

Gene Simmons believes Kiss could head into the studio to record their next album as soon as 2016.

Even though they saw it coming, Kiss were unable to stop the wheels from coming off their careers starting with the release of 1979's disco-influenced 'Dynasty.'

The members of Kiss have gotten animated for the new cartoon adventure Scooby-Doo! and Kiss: Rock and Roll Mystery, and you can watch an exclusive clip from the movie right here.

Listen to "Don't Touch My Ascot," the humorous new song Kiss recorded for the animated movie 'Scooby-Doo! and Kiss: Rock and Roll Mystery.'

Kiss' biggest and boldest shows yet would unfortunately mark the end of an era.
