Hocus Pocus - Focus (1971)
Want an example of strangeness in chart history? Today's track, a heavy Dutch Prog-spazz fest complete with yodeling, actually charted higher in the US(#9) then it did in the UK(#20)!
Beloved as a cover song by metal bands, this is hardly representative of what Focus could do. Their early recordings, before guitarist Jan Akkerman left the group, are some of the most out there "popular" music you will ever find. Pick up a few tracks at the old mp3 store and see if they are your cup of tea, then dive headlong into the insanity and skill that Focus encompass in almost every track they've ever recorded.
Two for the price of one, true believers: The album track and the slightly faster single version as well!!! Who loves ya?
