I absolutely agree with the review below, this is the essential ZZ Top album, yet it was always only available on CD with absolutely dreadful '80s mastering. This version sounds fantastic - back to the gorgeous natural warmth of the vinyl version. Buy it now and destroy your other CD copy.
But those live bonus tracks, they are terrible. Very cruddy. Why oh why do remastered CDs always seem to have to include a bunch of terrible live bonus tracks that no-one wants and which, as the reviewer below says, just leave a nasty taste at the end of a classic album. I was going to knock off a star for this but just couldn't bring myself to, Tres Hombres is too good for 4 stars!
Now, please remaster the other early albums which received the same '80s hatchet job..
