Oh, they "tried" to save the facades but in the end, they "couldn't" - yeah right!!!
As soon as House of Blues signed onto the deal it was obvious that we could expect a major HOB-Disnification of the exterior and should be ready to see something completely different than was approved.
So it's no surprise that all of sudden - oops - the facades "had" to go. The next step is a press release that says "well, now that we tried-but-couldn't save the old facades, we thought to ourselves, now is a good time to rethink the whole design of the exterior - with the help of the corporate branding team at HOB - we think we came up with something really great!" and then cue the picture of an Orlando or LA-style House of Blues transplanted onto Landsdowne.
For the record, I'm glad to see the old facades gone myself - and have no problem with a HOB-Bayou theme park motif. The Orlando HOB is a great place for corporate events and to see live acts - far better sightlines and amenities than the old Avalon.
