I finally bought this CD after hearing so many good things about it from various sources. I found this CD for cheap, and it contains both the MONO and STEREO mixes of the record. Although the CD is too mellow to be called a rock album by my standards, it is still very infectious. The production is lush and and inventive (for the time it was released... 1966!). It predates all the hippy stuff the Beatles did by almost 2 years! The liner notes are extensive and help put the whole thing in context.
