The Sachal Studio Orchestra, a Pakistan-based jazz group, has been taking the US and UK charts by storm.

The group was started by a London-based businessman in Lahore, who has put more than $2 million of his own money into building a state of the art studio for the musicians, who blend eastern and western styles, to record their music in.
