The ever popular Concerto for Double Bass in A major, here transposed to G major (Orchestral tuning) Just the piano part. Believed to be by Dragonetti but we now know it to be the work of the editor Edouard Nanny. 
 
I know there are many versions available but this one goes with the IMC edition and you  have to print it up yourself saving a fortune in postage!
