What is the VERY BEST CD album you've ever heard?

The CD that warms my heart and shows off the revealing nature of my Maggies is Take Five by Dave Brubeck on SACD.  I would also add I agree with Live at the Fillmore as noted above.

Mine would be " The Wonderful Sound of Three Blind Mice " by the Tsuyoshi Yamamoto Trio  I bought this CD back in 1995 and just recently I thought I would buy another one for back up I eventually found one and at the time The selling price was $300!

I am going with something I still play.  Supertramp' "Crime of the century".  Sonics still blow me away.

@czarivey Two CD's that belong in your collection:

Jimmy Smith - Dot Com Blues

Junior Wells - Come On In This House.

@hipsterjefe Graceland was the first disc I heard as well.  A gradeschool buddy invited me over to show me his dad's new CD player, and that was the only CD they had at that point.  

One of my favorites is Pink Floyd's Pulse double disc.  I typically hate live recordings, but I get excited every time I play that one.

I have a ton of other favorites, but a couple that stand out to me are Sponge's Rotting Pinata album, and the X-Files movie soundtrack.  I don't even know why those two are on the top of my head right now, but I have thoroughly enjoyed both and the production on both sound great..
