Mirkwood is a name used for two distinct fictional forests on the continent of Middle-earth in J. R. R. Tolkien's legendarium.
One of these occurred in the First Age of Middle-earth, when the highlands of Dorthonion north of Beleriand were known as Mirkwood after falling under Morgoth's control.
The other Mirkwood, and the more famous of the two, was the large forest in Rhovanion, east of the Anduin. This had acquired the name Mirkwood during the Third Age, after it fell under the influence of the Necromancer; before that it had been known as Greenwood the Great. This Mirkwood features significantly in The Hobbit and in the film The Hobbit: The Desolation of Smaug.
The term Mirkwood is taken from William Morris, influenced by the forest Myrkviðr of Norse mythology. Projected into Old English, it appears as Myrcwudu in Tolkien's The Lost Road, as a poem sung by Ælfwine. Tolkien also used the term Mirkwood in another unfinished work, The Fall of Arthur.
Forests play an enormous role throughout the invented history of Tolkien's Middle-earth and are inevitably an important episode on the heroic quests of his characters. The forest device is used as a mysterious transition from one part of the story to another.
Mirkwood was a British progressive rock band formed in early 1971 by guitarists Mick Morris and Jack Castle. The band's ancestry can be traced to the original Dover-based, Rolling Stones, a skiffle and blues band formed in 1956.
When Mirkwood's original drummer Steve Smith left, his replacement was Nick 'Topper' Headon, who occupied the drum chair for a year and a half, during which time Mirkwood supplemented their own gigs by working as support to bigger name acts including Supertramp. Topper Headon eventually left Mirkwood and joined The Clash. The band made its final appearance (at the Marlowe Theatre, Canterbury) in July 1978.
Mirkwood recorded one eponymous album of original material released on the Flams record label (PR 1067). Some years later, the Mirkwood album had become the most expensive listed in Record Collector magazine. It has since been re-released several times, most recently in 2008 on Red Admiral Records, (REDAD CDA556). A review of the album by Classic Rock Society magazine described it as " ..... a fine piece of work .... (combining) slick guitar work, thrilling vocals and imaginative composition and arrangements ...... from a band that could have gone on to great things".
Morris and Castle played occasional gigs together in the Kent area, and reunited in 2015 to release the album Boys From The Chalk.
