Recorded well before the free-flowing, psychedelic R&B of the Woodstock favorite "Going Up the Country," or the sinister, shimmering "On the Road Again," these mid-1960s studio tracks feature the prototypical boogie blues band Canned Heat in its infancy (though already with the line-up that included the guitar master "Blind" Al Wilson, which would see it through its most popular years). Blues classics like Willie Dixon's "Spoonful" and John Lee Hooker's "Dimples" display the Heat's youthful energy and enthusiasm; the legendary R&B bandleader and impresario Johnny Otis produces.
