Inertia is the second studio album by keyboardist Derek Sherinian, released in 2001 through InsideOut Music. This album marks the beginning of Sherinian's longtime collaborations with drummer Simon Phillips as well as guitarists Steve Lukather and Zakk Wylde. Using only the above description and what you know about the world, "Derek Sherinian released three studio albums before Inertia was released." is definitely correct, incorrect, or inconclusive?
