Was Free the greatest British blues band? Might seem an odd question, since after their first album they didn’t cover blues standards or even adhere much to regular blues forms. But a deep blues spirit pervades their music, especially in Paul Rodgers’ vocals and Paul Kossoff’s guitar. Call it Blues for Moderns. Kossoff’s slithering, fuzzed-out, behind-the-beat guitar playing in this song sounds (and feels) like he tore out his heart and gave it to you.
