InTune
InTune from LinkedIn is a rambunctious group of talented coworkers who have become known for their fun mashups and high-energy performances. Established in 2014, they found each other through a mutual love for music and are now one of the veteran groups of Techapella. They most recently engaged in a Pitch Perfect-style riff-off with The Vocal Network from Facebook to determine the best boy band of all time.
Check out their music videos on YouTube, and their page on Facebook.
