Diamond Dave hit the ground running with his 1986 solo debut Eat ‘Em And Smile.

That album had a raw, live-in-the-studio sound, courtesy of producer Ted Templeman and some of the greatest rock musicians of all time (Steve Vai, Billy Sheehan, Gregg Bissonette), but sophomore record Skyscraper – released 30 years ago today – was something completely different: a meticulous, layered, fussed-over project.

Vai was promoted to co-producer, Roth enjoying his energy and studio nous, and his influence is all over the record.

Vai told Classic Rock magazine recently about their working relationship: ‘We got on really well. We were friends. He listens and doesn’t assume to know everything. But it was his band. He made all the executive decisions. I’m very good at assuming a role and knowing where the boundaries are. I expect that from other people when they’re working with me.’

Vai took his time doubling parts, sculpting solos and thinking of the songs orchestrally. His playing is absolutely brilliant. He forensically explores every chord and adds humour too, an aspect missing from 99% of rock guitarists.

The more challenging compositions (‘Bottom Line’, ‘Hina’, the title track) rehearse the concepts that Vai would pursue on his breakthrough Passion And Warfare solo album.

So Skyscraper is musically rich but great fun too. Vocally, Roth has such a strong presence and he busts his butt trying to entertain.

Lead single ‘Just Like Paradise’ – described by Dave as his tribute to The Beach Boys – reached an impressive #6 on the US Hot 100, ‘Perfect Timing’, ‘Damn Good’ and ‘Stand Up’ are pure pop, co-written by Roth and keyboard player Brett Tuggle.

‘Two Fools A Minute’ is quite unlike any hard rock this writer has heard, basically a live-in-the-studio take with a succession of nutty mini-solos by Vai and Sheehan. It’s something akin to a heavy-metal show tune, complete with ‘cheesy’ horn section. I love Dave’s little ‘Sizzlin’ to the top!’ exclamation before Vai’s solo and his increasingly weird comments as the track goes on: ‘Where’s the drummer?…Nah, we can’t let Stevie drive…’

There’s a distinct lack of low-end on Skyscraper though. Billy Sheehan’s number was up. He left after the album’s recording and didn’t take part in the hugely successful, 10-month world tour. But he would take a lot of this album’s approach to his next band project, Mr Big.

Skyscraper divided critical opinion on its release but was a big hit, reaching #6 in the US and #11 in the UK. Happy birthday to a fun-filled and oft overlooked minor classic of the ’80s.
