Thanks for the Pearl Jam reference. There are three PJ releases that I know of that are available as hi-res downloads. Here's hoping more of the best rockers will release in hi-res.
The gold standard for rock musicians who care about hi-res is Steven Wilson. His recording and format selection is of the highest standard. Recommend Hand.Cannot.Erase. and The Raven That Refused to Sing as the rock multichannel hi-res standard. He has also remastered vintage recordings such as Aqualung and King Crimson, which are recommended. Also available as 2 channel downloads on HDTracks, etc. Please tolerate the hyperbole, but SW is the best!
