We all know about Macklemore. We've heard the song "Thrift Shop" countless times and watched him make history during this year's Grammy awards, when 33 gay couples wed to the tune of "Same Love." But what do we know about his sidekick, Ryan Lewis?

If these New Yorkers didn't know much about him before, he made sure that they know about him now!
