"Jonathan Glass is the real deal, an artist who gives his all to the purpose of realizing his deeply personal vision. In the nearly ten years that I’ve known him, I’ve admired his tenacity, openness to improvisational risk-taking, and above all, the vibrant, one-of-a-kind results."  - Dan Tepfer, Jazz-Pianist


"When I am performing in the city, it is always wonderful to see Jonathan Glass in the audience. His love of the musicians and the music is lovingly translated on his pages. I, like him, am a throwback to a very different time in music and in New York City. I've got a collection of his from over the years, and I'm grateful to have them." 
​- Rebecca Martin, Singer/Songwriter
