Johnny (guitarist/vocalist) of Attack Attack! recently left the band. He was my personal favorite member of the band, not only for his singing talents, but for the fact that he was one of the only founding members left.
It's always sad news when you hear about your favorite bands breaking up or losing members, but I like to look at it as an opportunity to hear something new! Not only from Attack Attack! but from Johnny. There's always a chance for something new to come. I'll update if I hear of anything else.
