There are at least five artists known as Constantine:

1) http://muppet.wikia.com/wiki/Constantine
(2014- )
Constantine is the world's "Number One" criminal and a doppelgänger of Kermit the Frog. He is the main antagonist in the film Muppets Most Wanted, along with his sidekick Dominic Badguy (aka "Number Two"). Constantine sets out to steal an enormous diamond. However, mayhem ensues when he gets entangled with the Muppet troupe on their European tour.

He is almost identical to Kermit aside from a few details. His pupils are shaped like Kermit's, but are slanted in toward each other at a sharper angle. Kermit's signature 11-point collar is duplicated, but Constantine's is notably shorter. The most distinguishable difference is a beauty mark on Constantine's face that he has covered up. Kermit is seen with the beauty mark while detained in a Russian gulag, presumably mistaken for Constantine. Constantine also has a strong Russian accent, which he disguised by saying that "Kermit" had a cold.

2)Constantine is a heavy metal/progressive metal band from Finland.

3) Constantine is a Greek guitarist who has played with bands in the Athens area, and released his debut solo album in 2010 entitled Shredcore. He plays a style largely influenced by players like Joe Satriani, Marty Friedman, Michael Romeo, Michael Amott and Zakk Wylde.

4) Constantine Maroulis is a former American Idol contestant, please see that page for that artist.

5) An acid folk band who released an album 'Day of Light' in December 2015 - all written by Constantile Hastalis and recorded with help from members of Of Wondrous Legends. From the Bandcamp;
"Constantine's debut LP 'Day Of Light' will lead you on a lysergic odyssey filled with sitar and swirling flute. The LP includes help from members of legendary '71 baroque folk psychedelic masterpiece O.W.L. (Of Wondrous Legends), including album art by Stephen Titra. This privately pressed psychedelic & acid folk inspired LP (housed in a charming gatefold sleeve) was only pressed in 300 copies!"
