This 20-track installment in the ongoing NOW series is undeniably impressive. There are no deep cuts here, no album tracks, and no surprises. Rather, the listener gets song after song of the finest hard rock of the 1960s and '70s. From the Who's "My Generation" and CCR's "Bad Moon Rising" to Mountain's "Mississippi Queen" and Rush's "Spirit of the Radio," listeners will surely be pumping their fists and shouting "Yes!" throughout the entire disc. Classic rock indeed.
