Phenomenal day with Aloe Blacc participating in Dr Ana Flavia Zuim’s clinical trial on laryngeal hydration and phonation threshold pressure — the stress needed to open the glottis to make a sound. Here Aloe tests, Fends, tests for two hours, then sings. Way more unforgettable than images can convey thank you Ana and Aloe for the best day ... @aloeblacc @anaflaviazuim @hellofend @nextbreathglobal
