Tomaso Albinoni
Tomaso Albinoni (1671-1751) was an Italian composer, perhaps most celebrated for his many successful concertos.
The most famous single piece attributed to Albinoni is the Adagio is G minor, however this was actually written by Remo Giazotto, perhaps based upon an Albinoni bass line extract.
You can find an accompaniment to that Adagio on this website, along with two of Albinonis most beloved oboe concertos. Links can be found below.
