(With thanks to Yesfans member downbyariver for the heads-up.)
According to this listing on Amazon, the Live At The Apollo audio release is scheduled for September 7th and can be pre-ordered, but only the digital version of the album. One would assume that if this listing has gone live then others will follow soon-ish if a physical release is also planned.
