I thought the original albums were just fine so I didn't bother with the remasters.
I see now that you can get
Hard Again,
I'm Ready, and
King Bee from Amazon for around $25.00 total. Considering that Amazon wants $18.00 for this new comp, anyone that has none of it may want to go directly to the 3 albums. You won't have the live tracks, but I imagine anyone that into Muddy will want that whole album anyway.
Anyone looking for just a taste can try
King Of The Electric Blues, with many of the same tracks. It's got only 15, but can be had for around $5 or $6 new from Amazon sellers.
