Although the Aladdin Hotel & Casino in Las Vegas is currently undergoing a massive facelift now that the property is being converted into a Planet Hollywood resort, at least one thing won't be changing--the sound system in the 7,000-seat Theatre for the Performing Arts. Designed and installed three years ago by A-1 Entertainment Services' Al Siniscal, with assistance from TPA Production Manager Craig Thomesen, the venue's L-ACOUSTICS loudspeaker system has been used on shows for Sir Elton John, Tim McGraw, Bob Dylan, Prince and many other top-tier acts.
