mosszuniga: Had to join @Lawrence Leo in this performance since he was one of the acapella user’s who inspired me to start doing One Man Pentatonix covers here! And also I have few collabs with him in my profile :) #Problem #Pentatonix #Cover #acapella #sing #harmony #harmonies #ptxcover #ptx #bass #singing #acapellaapp #collab #mossz
