Certifiable boasts a whopping 19 songs from the Police's 2007 reunion concert at River Plate Stadium in Buenos Aires, Argentina. Right from the first verse of "Message In a Bottle," Sting is singing with the well-preserved voice of a young man, hitting his high-notes with an effortless cool even more noticeably on the opening howls at the beginning of "Synchronicity II." Similarly, Stewart Copeland's drumming prowess hasn't lost any luster as evidenced by "Walking On the Moon" and technically he's a better player in that those live tempos don't speed up when letting loose on his signature reggae and ska-inspired fills. (If you've ever seen old live footage of guitar player Andy Summers yelling at Copeland to slow down, you might notice this right away). By "Roxanne" it's apparent that some of these songs are being played in a lower key so that Sting can hit the falsettos, but other songs like "King of Pain" and "Every Breath You Take" sound like the band hasn’t changed since 1983.
