We’ve got a whopper of a Peter Gabriel prize pack to give away to one lucky Slicing Up Eyeballs reader: 12 CDs, including his latest album, the orchestral ‘New Blood,’ which represents nearly his entirely discography, plus a lithograph of the ‘New Blood’ cover signed by Gabriel himself — all courtesy of EMI Music.

If you caught the ‘Late Show with David Letterman’ last night, you may have seen Peter Gabriel perform his classic ‘Red Rain’ backed by the New Blood Orchestra. However, he also performed a full hour-long concert from the Letterman studio that was webcast, which you can see here.

This week’s new releases include new, live and reissued albums, singles and EPs from the likes of Peter Murphy, Bjork, Peter Gabriel, Kate Bush, the Pixies’ Black Francis, The B-52s, Erasure and Talk Talk.

Peter Gabriel’s foray into classical music continues this fall when the singer follows last year’s orchestral covers album ‘Scratch My Back’ with a collection of symphonic reworkings of his own material called ‘New Blood’ — plus the ‘New Blood: Live in London in 3 Dimensions’ concert movie filmed this part March.

With a new orchestral album on its way, Peter Gabriel today announced he’ll bring his New Blood orchestra back to North America this summer for a 12-date tour that’ll see him performing classic songs such as ‘Red Rain,’ ‘Don’t Give Up’ and ‘San Jacinto.’

Although his catalog was just put back into print last month, Peter Gabriel is planning a full series of new reissues in 2011, including an expanded 25th anniversary edition of his crossover smash ‘So’ packaged with mixes, demos and new artwork.
