Collectables' ten-volume History of Rock series doesn't have the decades-spanning scope that the title implies; instead, it pretty much stops at the mid-'60s and covers rock's early years, with a few inclusions from the latter half of the '60s. While each disc contains 14 songs that are smartly chosen, it's the type of series that only truly appeals to two kinds of people: those who are looking to own these songs on CD for the first time, and the unfamiliar who want a decent introduction to the era. Highlights on the seventh volume include Mungo Jerry's "In the Summertime," the O'Kaysions' "Girl Watcher," Gogi Grant's "The Wayward Wind," Brenton Wood's "Gimme Little Sign," and Ohio Express' "Yummy Yummy Yummy." ~ Andy Kellman, All Music Guide
