I have written about the musical scene at RIT in several blogs over the years, but my fascination with the musical groups on campus is constantly renewed when I check out their shows, or see the concert recap online. Music at RIT is a dynamic community - song choices vary with the season, campus fads, and with the personality of the group. Most recently I viewed the Proof of Purchase rendition of “Below My Feet” on the RITstudents “Student Life” Youtube playlist. Founded in 2009, Proof of Purchase (“POP”) is the only co-ed a cappella group on campus. POP has performed with groups including the Buffalo Chips (Univerity of Buffalo), Premium Blend (Fredonia), and the Rusty Pipes (RPI).
