Got this from ultimate-guitar.com about the "after effects" of Live 8.
The Live 8 Effect
Although Live 8 was created for a good cause, it would be fun to see if the artists who performed possibly had an increase in album, supposes AudioAgression. As with the 1985 Live Aid, the bands that took part this year have seen their album sales exploding in the immediate aftermath of the music festival.
HMV has revealed that fans rushed to the shops yesterday (July 3rd) to purchase albums of the likes of Pink Floyd, who have seen album sales increase of 1,343%. The Live 8 effect is expected to continue as the week goes on, with HMV’s Gennaro Castaldo explaining: "This snapshot still shows that, like its predecessor 20 years ago, the Live 8 concert is having a marked effect on sales of featured artist recordings. It's likely this impact will become more pronounced throughout the week."
