More known for his various production monikers such as Tilt, Quivver, and Space Manouevres, John Graham helped define the sound of progressive house and trance in the late '90s. Few producers were as prolific or successful. Nearly every track he released became a huge anthem. He continued producing trend-setting tracks into the 2000s and began furthering his DJing career with a volume in the popular Tranceport series of DJ mix albums as Quivver. ~ Jason Birchmeier, Rovi
