I've had the privilege of hearing the great Robert Ross in person, and he is one amazing blues singer, guitarist, and harmonica player.
He has played with many of the greats and is often found touring throughout the New York metro area with the Robert Ross Band.
His gig calendar is here: http://www.robertrossband.com/gigcalendar, his videos are collected here: http://www.robertrossband.com/videos, and he's collected a bunch of audio files for your listening pleasure here: http://www.robertrossband.com/audio.
A real treat.
