A few weeks ago, Acoustic Sounds accidentally published the listing for an upcoming UHQR vinyl release of Steely Dan's Katy Lied mastered by Bernie Grundman. Shortly thereafter, an eagle-eyed fan on Steve Hoffman Forums found that by changing the numbers in the URL, one could find unlisted pages for both vinyl and SACD releases of every Steely Dan album album through Gaucho.
Both the SHF thread discussing these releases and the inadvertently published Acoustic Sounds pages have been deleted. But screen captures and Google Cache have preserved at least some of the information.
Needless to say, Analogue Productions SACDs of the Steely Dan catalog would become immediate contenders for the best sounding versions of each of these albums.
Keep your fingers crossed that the hidden pages on Acoustic Sounds represent real upcoming releases that will be made public shortly. Needless to say, I'll be punching every one of the SACDs.
