One of our earliest projects but also one of our highest profile is www.UniversalMusic.com. Approached in the fall of 2007 by Fearless Concepts (New York, NY) looking to subcontract out the redesign of Universal Music Groups' (UMG) (New York, NY) main public web site. UMG had seen the headway that Drupal was making in the music industry and as the world's largest recording company; they decided it was time to do the switch.
UMG's art department provided the Photoshop work that was the basis for the site's theme. LiquidCMS created this theme and all the underlying functionality within the site. One of the tightest schedules we have had to work with; but managed to have the first phase of the project launched within 4 weeks of the project kickoff.
Later phases added the custom search page and a complex video feed mechanism. The feed module (which predated Drupal's existing Feeds module) pulls in RSS data from UMG's video warehouse provider and uses this to auto create both artist profile pages and all the video content you see on the site.
NOTE: in April of 2012 UMG abandoned Drupal for their site and went to a less attractive site with far fewer features.
