There are a few I know and am glad they happen to be my favorite bands as well.
- Porcupine Tree/Steven Wilson/related projects : Probably the best out there.
- Tool : Although I am not a fan of Microsoft or their closed source/proprietary technologies, but anyway Lateralus was produced using HDCD encoded technology...goes to show their concern for good recording.
- Nine Inch Nails : Of course ! Their album The Slip apart from being available free of charge, is available officially in FLAC (with different bitrates and quality for specific classes of listeners, audiophiles are given priority as well ! )
It would have been probably better had their been no iPods or mp3 players, but anyway that is a subjective issue.
I hope members will contribute names of artists/bands they know who still care for good production & recording.
