Rami Hatem is a Oud player out of Sweida, Syria, in the Druze area, Farid El Atrache's home city. Hence his style is very Farid. If you like Farid
style taqsim, you'll like Rami.
I don't know if he is a "professional" in the technical sense, but I'm sure he could be if he wanted.
Here is an example. He is mainly active on facebook.
