Deep Rock

There has been no shortage of Deep Purple compilations over the years, but unlike some of the British hard rock legends' contemporaries (Sabbath, Zeppelin, etc.), they've managed a fairly consistent stream of output since their 1968 debut. Rhino's A Fire in the Sky, a 40-track career retrospective that includes at least one song from every studio album through 2013's Now What?!, is easily the most comprehensive anthology that the band has released to date – a more manageable, largely singles-oriented 20-track version is also available, as is a triple-vinyl edition. Despite cycling through too many lineup iterations to mention, the band has consistently adhered to the heavy blues-rock foundation that made career highlights like "Hush," "Smoke on the Water," "Highway Star," and "Woman from Tokyo" so essential.

After satisfying all of their classical music kinks with keyboard player Jon Lord's overblown Concerto for Group and Orchestra, Deep Purple's soon to be classic Mark II version made its proper debut and established the sonic blueprint that would immortalize this lineup of the band on 1970's awesome In Rock…
