There is more than one artist called Quartz. 1) Quartz came out of the British hard rock hotbed of Birmingham to join the New Wave of British Heavy Metal movement in the late '70s. With a lineup that included John Bonham-associate Mike Hopkins and future Black Sabbath keyboardist Geoff Nichols, they were actually founded under the name Bandylegs but changed when Jet Records showed interest in the band.
With their debut LP "One Sweet Life", London based duo Brotherly come at broken-beat from a distinctly dark and jazzy angle. Featuring the vocal talents of Anna Stubbs and multi-instrumentalism of Rob Mullarkey along with appearances from UK Hiphop luminary Ty and soul chanteuse Eska, the outfit effortlessly straddle urban genres whilst holding on to a strong and unique identity. Affiliations with Zero7 and Two Banks of Four also show signs of heavy influence in the music.
Q Project (Jason Greenhalgh) is a drum and bass music producer. He makes up half of Total Science, along with fellow producer Paul Smith (who produces under the name Spinback). He is well known for his release "Champion Sound", a popular jungle anthem of the 1990s.
Nu:Logic are Dan Gresham (Nu:Tone) and his brother Matt Gresham (Logistics). Their first release, "Warriors/Not The Only One", in 2003 was the first release which Matt Gresham was involved in, and in 2004, they were featured on Hospital Records' "Weapons of Mass Creation Vol. 1". From then on, Logistics and Nu:Tone went on as solo artists.
They came back in 2010 with the New Technique EP.
