I teach elementary music. With Brandon's help, I was able to record the alto part for our holiday musical into the purchased practice-trax, and double myself singing on piano. Then, we adjusted the volume so it stood above the other parts, but did not overpower. This made a world of difference to my 3rd and 4th grade harmonizers, both students and parents loved it! I absolutely could not have done this without Brandon. He is professional, easy to work with, and a fine musician in addition to his technical skills in the studio. His rates are reasonable and I highly recommend him for any studio project, or lessons!
