Weekdays for Rochester’s Marco Amadio are spent at his day job at Xerox. Evenings and weekends are spent serenading audiences. It’s hard to not stop and stare in awe when you hear the smooth vocals and effortlessly talented piano playing by the musician who can be found performing in piano bars and concert venues throughout our region. Amadio describes music as medicine and singing as his form of service to others. Amadio joins this edition of Need to Know to his musical journey.
