Kasra is an integral part and prominent figurehead in the UK underground scene. Using his own label Critical as a vehicle for musical expression, Kasra has been responsible for supervising, nurturing and participating in the growth of high quality and extremely fresh drum and bass, from its early beginnings to what it is now - a highly eclectic club culture. In the past five years, Critical has created a unique identity that is revered the world over and has ultimately left an undying mark on the drum and bass scene.A defining moment in Kasra's career came in 2001, when the pursuit of tempering the dominant hardness of drum and bass with a warmer musicality led him to founding Critical - a label that instantly created a unique identity for itself by consistently putting out high quality music.

At a time when new labels were popping up every day and failing after three months, Kasra put both heart and soul into the imprint which proved only as a testament to his ability to rise above the negative context and turn what seemed like inevitable failure into epochal success.

As Critical grew, as did it's popularity; several prominent producers seeked a release on the definitive imprint resulting in various tracks, produced by Calibre, Silent Witness, Break, Young Ax, Breakage, Chris Su, Bungle, Mathematics, Delta & Format, Sys X and Ill Skillz
