April 16th was a British traditional heavy metal band formed in 1982. They only released one album called "Sleepwalking" in 1988, making them too late to be a part of the NWOBHM scene. The band were forced to drop out of the frontline of the rock business for financial reasons in 1991.
These are photos from concerts where April 16th played, so they may be of other bands that played the concert as well.
