"Rob is one of the rare guys in the industry that is very generous with his time. He carefully listens to mixes and gives honest, detailed feedback on how to improve the mix, resulting in a much more pro sounding track upon completion. The mix analysis alone is worth the price of admission...a great sounding master for release, is just an added bonus!!"
