One of those online dictionaries defines "freakbeat" as "a sub-genre of rock and roll music developed mainly by harder-driving British groups, often those with a mod following during the Swinging London period of the mid to late 1960s".
Fair enough. This review is written by someone who used "The Rubble Collection" of UK freakbeat as the soundtrack to painting a dining room wall. There are 10 discs in that box set and, no, it didn't all of them to get the job done. Almost.
The point is that if you don't know the tag, you'll know th sound. Odds are you've probably heard, latched onto and loved a freakbeat band without consciously knowing it. In which case, you're a candidate to be equally besotted with The Galileo 7.
