I have been a fan of Osmani soundz from the very time I heard about him on Adil Ray's BBC Asian Network show years ago. The track that I heard then is still one his most haunting creations called 'Lushmeena' from their album - Eastern Drum and Breaks.
The track puts together a Lata Mangeshkar sample (also featured on Yash Raj Films introductory melody) with some deep drum and bass. Though already a few years old, IMHO it is a classic that's going to remain current for many many years to come.
I also got to see OS spin live at the Jazz cafe after Nitin Sawheny's performance and it was amazing to see people go into a trance on the small dance floor.
