I thought this meant that she was recording her new record. I've just googled LaLa Land and it's a record studio, I'm not sure that it was a show, but a session for Euphoria. At least that's how I read it after putting it together with this tweet:
@VanessaCarlton: Wonderful to do some records in Louisville. With such fine gentlemen. Also, thanks to Dr Laufer who gave me drugs w a smile at 8 am. Worked.
