that's right, although from what's been posted elsewhere Atmos mixes of Aerosmith's Classics may be upcoming?Aerosmith catalog is now controlled by UMG
fwiw i omitted a number of other possibilities, including the Simon & Garfunkel and Paul Simon solo Quads because.. well, it just feels like those will never happen unless the artist permits it.
i honestly feel like we have a better chance of seeing some Bob Dylan, Edgar & Johnny Winter and Barbra Streisand Quads before we see any Paul Simon titles but i'd love to be totally wrong!
there's other Sony Quads i forgot to mention that sadly i also feel have a slim to nil chance of reissue, including a couple of Harry Belafonte Quads (1 Japanese only, the other previously unreleased) and Phoebe Snow's delightful "Second Childhood" SQ LP only Quad.
