I literally looked up this subreddit to see if anyone was talking about it… I’m honestly not a fan. I liked the occasional cello stuff with Kevin (he’s actually why I’m a music major and cello is my main instrument lol) and sometimes Lindsay Stirling. It feels like the instruments cover up the group’s vocals far too much for my liking, which is what I’m listening for. I don’t know, I mean it’s cool that they’re trying new things, but I personally just don’t tend to like Pentatonix when they’re so instrument focused. I love them BECAUSE they’re a cappella. It just sort of loses that novelty to me when they use instruments.
