Alessandro Scarlatti was one of the major Italian baroque composers, with a prodigious output, particularly early operas. However, his instrumental pieces are nothing to sneeze at. I've picked two of his shorter works this morning; you'll find many more on YouTube if you like them.
First, here's his Sonata for Flute, Strings and B.C. No.22 and No.23.
Next, here's a live performance of his Concerto Grosso No. 3, played by the La Spagna baroque orchestra. You'll note how much smaller a baroque orchestra is compared to a modern one, and how many instruments didn't exist in those musical times.
I hope you enjoyed the change of pace.
