Well, it's really just me. I'm a bass player that can play a little guitar and sing a bit. Almost everything is recorded in my home studio and I usually try to do the best I can.
I wrote the piano thing kind of like a lounge bit. I'm not a piano player but I liked the way it sounded. I changed it because a friend didn't like one of the parts so I just completely re-recorded it. I still need to change the guitar part, though.
