DTE Energy Music Theatre is a 15,274-seat amphitheater located in Clarkston, Michigan. Originally built by the Nederlander Organization in the 1970's, it was originally known as the Pine Knob Music Theatre, due to its proximity to the nearby Pine Knob ski area and golf course. The name was changed before the 2001 concert season when DTE Energy (the parent company of Detroit Edison) purchased the naming rights to the amphitheater in a ten-year, $10 million deal.Despite this change, many people still continue to call the venue "Pine Knob", "The Knob", or "The Hill". The amphitheater is currently owned by Palace Sports and Entertainment, owner of the Detroit Pistons, The Palace of Auburn Hills and the historic Meadow Brook Music Festival. Annually, the music theater has consistently ranked among the top-selling outdoor concert venues in the nation.
The amphitheater held its grand opening in June 1972 with an Andy Williams concert. However, on June 25, 1972, a few days before Williams' appearance, there was a "pre-opening" concert featuring teen idol David Cassidy. The original sound system was novel in its day, a huge theatrical performance system designed for an outdoor theater with a custom console and large-array distributed speaker system.
