Query: Just buy Salvation and get the entire performance

Shock and Awe is essentially an abridged version of Salvation. Shock and Awe is missing a lot of material. The only reason I can think of to buy this over Salvation is if you want the bits broken up into shorter tracks. The tracks on Salvation are a bit long. But still, you'd be missing half of the performance. Skip this one. Get Salvation.
