Mr. Peter Hayden

enPHin aka ENPHIN (formerly PH and Mr. Peter Hayden) is a Finnish experimental metal band often filed under post-metal, space rock or psychedelic doom. The band was formed in Kankaanpää, Finland in 2000. On September 25, 2015, before the release of their fourth album, "Eternal Hayden" (2017), the band began to refer to themselves just by their logo, the PH-monogram, leading to confusion what the band should be called. Since then all variations from Mr. Peter Hayden to PH have been used. They are considered a part of the Wastement collective along Dark Buddha Rising and Oranssi Pazuzu.
On April 16, 2021 the band announced the name change again to enPHin aka ENPHIN - and that the band will play few last concerts as "PH" (the last concert under that name was on October 1, 2021) before releasing an album on Pelagic Records under the new name. On March 23, 2022 first piece of music under the ENPHIN moniker was released as "Cut Flesh", first single from "End Cut" album.
