More than 30 years after their inception, English neofolk kings Sol Invictus release their long-awaited new album, "Necropolis", described by the group's dean Tony Wakeford as "a record based on and brought forth from London and the serpent Thames that snakes its way through its heart" and possibly the final release from a band revered as progenitors of a dark and desperate sound.Sol Invictus is one of the most prolific and influential bands associated with neofolk or apocalyptic folk, a form of experimental music which emerged in punk rock circles in the 1980's, blending elements of folk and industrial music with dark themes of decay, decline, and/or the destruction of Western civilization. Along with Current 93 and Death in June (both of which included Wakeford as a member), Sol Invictus has both created and guided the genre, steering it forward through to this day. Latin for 'the unconquerable Sun', Sol Invictus has released over a dozen albums since the mid-Eighties, chronicling an evolution from raw, post-punk dark folk to increasingly sophisticated arrangements.A quasi-conceptual album centered on Wakeford's feelings of a declining London ["London was once the apex of an empire but it is now the playground of other empires that have superseded it."], "Necropolis" could be called a eulogy to England's capital. Sol Invictus titled the record after The London Necropolis Railway, a railway line that has connected London with the Brookwood Cemetary since 1854. But the moniker is also a nod to Wakeford's perception that the town is now "a London of mausoleums and masonry" and "a city haunted by the customs and crimes of the dead and the living.""Necropolis" features guest guitar from Don Anderson (ex-Agalloch, Khorada) who previously lent his skills to Sol Invictus' 2014 release, "Once Upon A Time". The group around Wakeford continues to explore the psychedelic side of dark folk, using acoustic guitar as a foundation enriched with piano, flute, violin, electric guitar an drums among other instruments and – for the first time – the singing of The Green Army Choir.
