There are three artists named Panopticon:

1) Panopticon is a one-man atmospheric black metal band from Louisville, Kentucky, United States of America which holds anarchist beliefs. The band was formed by Austin Lunn in 2007, and in early 2008 he left his other band Anagnorisis to focus all his attention on Panopticon. Their only release is a self titled full length released in 2008.The band is influenced both by early BM like Darkthrone and Mayhem and crust bands such as Amebix.

2) Panopticon is also a Jazz band. "To Be In Music" is PaNoPTiCoN's only goal.
This project idea emerged while Domenico Solazzo was recording his latest album, "Multiply", in which he invited several other musicians to a creative partnership. Some collaborations sounded better than expected hence their will to make it big and live! Inspired by the great mastery of 70's electric jazz improvisers and pioneers, PaNoPTiCoN is a sonic laboratory that takes life on stage only, where no one knows what to expect, including the musicians themselves ! Improvisation at its extreme best articulated around three axis: mood, groove and melody. At this moment, there are no core members. The PaNoPTiCoN's formula is an open invitation to anyone willing to dive into the most beautiful mystical forms of music.One show after another, the music played by the band should and will be different as the band itself!

3) Panopticon is a Progressive Metal band formed in Brighton, UK, with influences stretching as far as Rush, Children of Bodom, Tool and Racer X.
