The second of the three classic DP cds. The debate about whether it's better than Machine Head or In Rock is irrelevent really. In Rock, Fireball & Machinehead are three of the most important albums in Rock. Any fan of 1970s rock music has to own these. Anyone who likes Smoke on the Water or Child in Time should own them as well or you will be missing out on one of the greatest musical experiences you are ever likely to have. If you've never heard the full CDs you will be surprised at the sheer variety and quality that DP produced over this brief period.
