Ethan just let me know that the main Warner Bros Records website, http://www.warnerbrosrecords.com (or http://wbr.com), is a Drupal site. Furthermore, rumor has it that the design was done by Prod4ever and that the Drupal integration was done by AlianDesign. Well, it looks smashing!
Ethan is the Head of Technology at Warner Bros Records, and last time I met him, he was looking to hire more Drupal talent. People like Madonna, Metallica, Paris Hilton and the White Stripes work for Warner Bros Records, so you'd expect a great work environment. ;-)
