That's pretty damn sweet! Congrats. What type of music? I used to play drums. The only reason I say "used to" is because I haven't in years. Are you guys on SoundCloud?
There's nothing wrong with enjoying "ladies nights" or any other night as long as you enjoy the company you have. I live a life of "guys nights" and "guy days" and having a blast. Enjoy the time while you have it.
