It was a great era in terms of the music, the record sleeves, the videos, the performances, Kylie's voice sounding stronger and not multi-tracked, all brilliant. I was 14 at the time and think Kylie 'came of age' at the perfect time for me.
What was less good was the backlash that appeared in November 1990, where she won lots of 'worst' awards at the Smash Hits Poll Winners Party, and the magazine had it in for her pretty much from that moment on, culminating in the dreadful Madonna/Minogue article, which was very early 90s 'let's pit women against women because they've both danced in front of flames and worn bras'. So although it was a fantastic era to experience, the album only getting to 9 and no number 1 singles made it feel like Kylie really had to work hard to stay where she was.
