As the title suggests, A Thousand Suns: Live Around the World is a concert recording of Linkin Park's 2010 album. But fans should take note: This isn't a single performance, but a simulated one, with tracks culled from various stops along the band's 2010-'11 world tour. What's more, there's music missing. Granted, the absence of moody segues such as "The Radiance" and "Fallout" is minor. That said, why isn't "Robot Boy" here? It might not be arena material, necessarily, yet the four-minute number is far and away one of the group's most interesting stabs at ambient-tinged electronic rock.
