(1984–1994) Reunions and breakups

In April 1984, eight years after the demise of Deep Purple, a full-scale (and legal) reunion took place with the "classic" early 70s line-up of Blackmore, Gillan, Glover, Lord and Paice. The album Perfect Strangers was released in October 1984. A solid release, it sold extremely well and included the singles and concert staples "Knockin' At Your Back Door" and "Perfect Strangers". The reunion tour followed, starting in Australia and wending its way across the world to the USA, then into Europe by the following summer. Financially, the tour was also a tremendous success. The UK homecoming proved limited, as they elected to play just a single festival show at Knebworth (with main support from the Scorpions). The weather was bad, but 80,000 turned up anyway.

The line-up then released The House of Blue Light in 1987, which was followed by a world tour (interrupted after Blackmore broke a finger on stage) and another live album Nobody's Perfect (1988) which was culled from several shows on this tour, but still largely based around the by-now familiar Made in Japan set-list. In the UK a new version of "Hush" was released to mark 20 years of the band. In 1989, Ian Gillan was fired as his relations with Blackmore had again soured and their musical differences had widened too far. His replacement was former Rainbow vocalist Joe Lynn Turner. This line-up recorded just one album, Slaves & Masters (1990) and toured in support. It is one of Blackmore's favourite Purple albums, though some fans derided it as little more than a so called Deep Rainbow album.

With the tour done, Turner was forced out, as Lord, Paice and Glover (and the record company) wanted Gillan back in the fold for the 25th anniversary. Blackmore grudgingly relented and the classic line-up recorded The Battle Rages On, but tensions between Gillan and Blackmore came to a head yet again during an otherwise stunningly successful European tour. Blackmore walked out in November 1993, never to return. Joe Satriani was drafted in to complete the Japanese dates in December and stayed on for a European Summer tour in 1994. He was asked to join permanently, but his record contract commitments prevented this. The band unanimously chose Dixie Dregs/Kansas guitarist Steve Morse to become Blackmore's permanent successor.
