'So,' which was released in 1986 (hence the '½') is the ex-Genesis frontman's biggest selling album. Led by the No. 1 single 'Sledgehammer' and its iconic video, 'So' has sold over 5 million copies in the United States and reached No. 2 on Billboard's album chart. In addition to 'Sledgehammer,' three other songs from 'So,' 'Big Time,' 'In Your Eyes' and 'Don't Give Up,' charted on the Billboard Hot 100.

We're sitting on our hands waiting for more information about this. Who knows what outtakes, remixes or concerts Gabriel will be able to dig up for this new edition.
