There are two bands that use the name the Underneath. One is a Japanese rock band formed in 1996, previously called Transtic Nerve and reformed under that name in 2007 and now (since 2010) known as defspiral.
These are photos from concerts where The Underneath played, so they may be of other bands that played the concert as well.
