A1 Bassline (Christian Sibthorpe), co-founder of Tighten Up Records and well known mostly for releases on his own label, has his latest single Buoyancy out now on Claude Von Stroke's Dirty Bird.

His musical aspirations originate from genres such as garage, a sound he grew up with from an early age (his father, founder and features editor of Rave Magazine, managed garage/2step pioneer Dem2, AKA US Alliance), and drum and bass. He was a regular attendee of "Technicality", a forward thinking club night paying homage to the metalheadz blu note night. Along with A1, Ben UFO was a regular.

Although he makes music under the house banner, you can clearly hear these influences in all of his own material.

Essex born, but growing up just south of Croydon, he would (generally with school friends Kavsrave and Joy Orbison) frequent record shops such as the legendary Big Apple, Swag and secondhand store Beanos, buying garage, grime and drum and bass records.

Having had his first 12" release at the age of 17, things have certainly come a long way, since then having numerous singles out and touring the world.

To some Djs' disappointment, as many stake this claim, A1 Bassline (always thinking ahead) was the first person to play out Joy Orbison's Hyph Mango in any capacity.

His sound has progressed over the last few years to something he is more content with now. His latest few releases have been played by top Djs across the board leading him proudly to the signature of Dirty Bird.

With a run of great reviews and support from Dj Mag, iDJ, Fact, Knowledge, Resident Advisor….. and Dj support from a number of big names from Radio 1,XFM, Capital, Rinse FM and many more. 2011 has so far been a good year for A1 Bassline and has really brought his sound to the fore.

With plenty of new material in the pipeline the future is looking good.
