Answer
Blackmore rejoined Deep Purple in 1984, after a seven-year hiatus. His return marked a significant turning point for the band, as they had struggled to find success without him. With Blackmore back in the fold, Deep Purple released the album "Perfect Strangers" in 1984, which was a commercial and critical success. The band continued to tour and record throughout the 1980s and 1990s, with Blackmore remaining a key member.
