HDTracks are ramping up more popular releases. Demand must be growing and in a similar vein to the way CDs were released in their early days, more and more "classic" rock / pop albums are now coming out in glorious HD quality. And, despite their age, it does work - my HD copies of Rush's Moving Pictures and Steely Dan's Gaucho sound great, despite being recorded well before 24 bit digital had been thought of!
Elton John's Goodbye Yellow Brick Road
Eric Clapton's Slowhand
Beck's Sea Change
And lots of Rolling Stones
p.s. Not HD, but Hed Kandi's latest Serve Chilled: Electronic Summer is now available from Juno Download in CD quality WAV or FLAC.
