Yep, the "upcoming" box is where I saw it listed. Just d/l'd it, look forward to my review in the next What's Spinning thread brraaaaasskkkiiii.
They should just begin releasing "complete sessions" box sets for Hendrix. The archival releases are scraping the bottom of the barrel so thoroughly that the only stuff left isn't really worth releasing on it's own. But if they put out "literally every recorded piece of material featuring Hendrix presented chronologically Volumes 1-30" box sets they could double down by appealing to the completists and the box set fans while teasing "new" and "unreleased" material that wasn't worth releasing on smaller sets while also getting people to buy tons of stuff they own already, but because it's "complete" fans will still shell out the cash. Seems like the trend these days.
