Disraeli Gears is viewed as the masterwork of the all-star British rock trio known as Cream. But on the double-album followup Wheels of Fire, released a year later, their music positively boiled over. One record was filled with studio gems ranging from landmark hits (White Room) to blues variations (Sitting on Top of the World) to originals that pulled all kinds of psychedelic chamber-style punches (Deserted Cities of the Heart). The second disc of Fillmore West live recordings sported blues jams (Spoonful, Crossroads) full of ragged instinct and raw psychedelic fury. A volcano of an album.
