Best known as the frontman of Dark Star and guitarist with Levitation, he has also released solo material as Mikrokosmos (stylised in all lowercase), which was produced by Tim Smith.

Hayes appeared as part of the band on their 1992 concert film All That Glitters Is a Mares Nest (in which Tim Smith refers to him as a woman) and made writing and recording contributions to their studio album Heaven Born and Ever Bright (1992).

Following the disbanding of Dark Star in 2001, Hayes toured with the Pet Shop Boys and worked as a guitar tech/tour/production manager for the likes of My Bloody Valentine, Kula Shaker and David Cassidy.

[13] In 2011, Hayes organised and compiled the tribute record Leader of the Starry Skies in aid of Cardiacs frontman Tim Smith (who had suffered two strokes in 2008 which left him paralysed down one side of his body and unable to speak).

[1] He also toured with a stage version of Macbeth in 2011 and 2012, produced by Platform 4 and described as "a taut psychodrama that crackles with a wild electricity, brought alive by the sonic experiments of composer and guitarist Bic Hayes and sound designer Jules Bushel".

[14] More recently Hayes has been involved in the Brighton-based improvisational instrumental psychedelic band ZOFFF (previously known as Light Specific Data or LSD-25)[15][16][17] and with MUMMY (a duo with his partner, the singer Jo Spratley).
