There are at least two bands with this name:

1) Dwarrowdelf is a one-man musical project from Southampton, walking the utterly untrodden path of Tolkien-based epic black metal. Formed in 2017, the band's first release was EP Of Darkened Halls, that entirely used Tolkien-written lyrics. Dwarrowdelf released its debut full-length album, "The Sons of Fëanor", on 30th April 2018 via Wolfspell Records. A follow up, "Of Dying Lights" was announced for 30th March 2019, to be distributed by Flowing Downward.


2) During the early 1990s a ritualistic act was performed in the country of Norway to eliminate the christian plague and bring forth the first Black Metal band. With the final burning of the Fantoft Stave, eroded from the bowels of Hell itself came forth Dwarrowdelf. Read more on Last.fm.
