1 electric cellist (if you're interested, it's the NS Design electric cello), 13 singers and 2 violinists!
So a few weeks ago I recorded the backing track for Sia's Cheap Thrills on Acapella App and asked if anyone wanted to sing with me. Again, I was blown away by the talent of these people!!! People who I don't even know! Grateful and happy to collaborate with these people on this app.
