Hello joelman!
Yes, you write the artist's name (in this case The John Butler Trio) and then you write the venue's address. If the venue is close to where you live, you can send it, as BABii_ANG3L stated, about 2 days before they are scheduled to perform. {thumb2}
Also, make sure the venue passes on fanmail before you send something like a CD case! You can check venues that do/don't pass on fanmail by

Good luck joelman!!
