Deep Purple’s longevity is remarkable on a number of levels. Aside from a relatively brief split between 1976 and 1984, they've been a working band since 1968 – a striking achievement, attributable in part to their willingness to forge ahead creatively rather than coasting on past glories, and to adapt in the face of personnel changes.
Anyone familiar with their history will know that these two elements have not only worked in parallel on many occasions, but have often sparked fresh, innovative Purple patches.
