A 21-track distillation of the three-disc Jethro Tull box set 20 Years of Jethro Tull, this collection has a few rarities, yet its focus is on the songs every casual fan knows -- album rock hits and rarities, all assembled on one hits compilation. The more selective listener -- and there are those among the casual listener (such is the character of art rock fans) -- may find that this focuses too much on the accessible material, but anybody that learned to love the Tull through AM radio will find this a very good compilation overall, even if it's heavy on macho attitudes.
