I stumbled across this Italian pianist Francesco Parrino and my wife and I are really enjoying his uploads. He does mostly contemporary pop covers but has a nice variety of older stuff as well. Here is a fun arrangement of Fly Me To The Moon.
He actually sells the music for his arrangements and has another YouTube channel with tutorials on his arrangements.
Here is his website for more information about his training.
I love his versatility, enthusiasm, and quality of recordings. I'll probably end up adding some of his albums to my iTunes library.
