London's Rebetiko (Baglamas Instrumental) Arranged for String Quartet (Demo)

I have performed with a string quartet twice in my life (and still haven't uploaded the videos:-) in Scotland. 

I am invited for a third time next year. 

So I started learning how to arrange my instrumentals for a string quartet. 

Above is my first attempt, the London's Rebetiko. Recorded using a midi sequencer.

And here's a link to the original recording on Bandcamp.
