From what I've read the 1994 remaster cds sound the closest to the original editions but I think it's missing WCD.
P.S. Maybe this Genesis News topic explains better...
indeed! The series only features the studio and live albums from Trespass through Three Sides Live.
Since this era is my favorite one from Genesis, I would love if the band, or some distributor like Disk Union, would release a box unifying these releases with these masters.
