"Freakbeat" is a term sometimes given to certain British Invasion acts closely associated with the mod scene during the Swinging London period, particularly harder-driving British blues bands of the era that often remained obscure to US listeners, and who are sometimes seen as counterparts to the garage rock bands in America. Certain acts, such as the Pretty Things and the Creation, had a certain degree of chart success in the UK and are often considered exemplars of the form. The emergence of a relatively homogeneous worldwide "rock" music style marking the end of the "invasion" occurred in 1967.
