My Chemical Romance announced that they were breaking up on the alternative rock band’s website on Wednesday.

"Being in this band for the past 12 years has been a true blessing. We've gotten to go places we never knew we would,” the announcement read. “We've been able to see and experience things we never imagined possible. We've shared the stage with people we admire, people we look up to, and best of all, our friends. And now, like all great things, it has come time for it to end. Thanks for all of your support, and for being part of the adventure."

My Chemical Romance was founded by frontman Gerard Way after being prompted to form a band after the attack on the World Trade Center in 2001. Throughout the group’s 12-year run together, they released four studio albums. Their last album was Danger Days: The True Lives of the Fabulous Killjoys, which was released back in 2010. MCR had been touring together as recent as mid-2012.

The band, comprised of Way on lead vocals, bassist Mikey Way, and guitarists Ray Toro and Frank Iero, saw success with their second album, Three Cheers for Sweet Revenge released in 2004, which was their first platinum effort. Their third album, The Black Parade, also went platinum, and saw their single, “Welcome to the Black Parade,” become a top-10 pop hit.
