Why is Lovesexy probably Prince’s least-heralded, least-mentioned album of the 1980s? Even Dirty Mind, Controversy and Batman seem to get a better rap these days.

The cover photo said it all – this was Prince’s ‘spiritual rebirth’ album, and you were either in or out.

Lovesexy was also a response to his alleged dabbling with psychedelic drugs (apparently taking place on 1 December 1987) that shook him to his core, and also a response to the highly sexualised, uncharacteristically angry Black Album. He once said, ‘I realised that if I released that album and died, that’s what people would remember me for. I could feel this wind and I knew I was doing the wrong thing…’

So Prince shelved The Black Album – Lovesexy was the speedily-recorded, musically-rich antidote. It’s one of the most challenging albums of Prince’s career but also one of the most rewarding. From the opening synth chords and Ingrid Chavez’s brief ‘poetry’, it’s clear that this is something pretty special. And different.

The horn arrangements are downright loopy throughout. Discordant, dissonant. Instruments are layered to sometimes disconcerting effect. Comparisons to Zappa are not inappropriate. Prince also dials in a lot of his spiritual concerns, with God competing against the Devil (or ‘Spooky Electric’), the purity of the spiritual life competing against the sins of the flesh. With a few jokes.

For many, including saxophonist Eric Leeds, the result was a bit of a mess: ‘I thought it was going to be a great album, but when I heard the final mixes, I was very disappointed. I thought he had completely over-produced the music…’

But the savvy so-and-so that Prince was, he was also careful to throw in three of his most irresistible, ‘throwaway’ pop tunes – ‘Alphabet Street’, ‘Dance On’ and ‘I Wish U Heaven’ – and one of the finest ballads of his career, ‘When 2 R In Love’.

At once scary, profound, silly, funny, romantic and outrageous, Lovesexy still sounds fantastic 30 years on. It was Prince’s first UK #1 album and spawned probably the best tour of his career.
