One of the greatest heavy metal summits of all time took place on May 20 and 21, 1985 at Los Angeles’ A&M Records Studio. The goal: creating a charitable single, “Stars,” later issued by the project known as Hear ’n Aid. The cause was raising money for famine relief in Africa — as it had been for recent efforts undertaken by pop musicians, in both the U.K. (Band Aid) and the U.S. (USA for Africa), but that’s where the similarities ended and Hear ’n Aid stood alone.

Band Aid sowed the general seeds for Hear ’n Aid’s existence back in 1984, along with a 48-hour radio telethon hosted by L.A. radio station KLOS, specifically, which happened to be attended by Dio members Vivian Campbell (guitar) and Jimmy Bain (bass), among many other stars. Together, the duo crafted a new song and asked their boss, Ronnie James Dio, to help with some lyrics and, before anyone could count to 11, heavy metal had an answer to Band Aid's “Do They Know It's Christmas?” and USA for Africa's “We Are the World.”

Its name was “Stars,” and the roll call of hard rock and metal stars eager to lend their talents to those sessions was nothing short of astonishing. In common with those pop music efforts, “Stars” witnessed a string of leather-lunged singers trading lead vocals lines -- namely Dio, Judas Priest’s Rob Halford, Blue Oyster Cult’s Eric Bloom, Quiet Riot’s Kevin DuBrow, Queensryche’s Geoff Tate, Y&T’s Dave Meniketti, Rough Cutt’s Paul Shortino and Dokken’s Don Dokken, as well as dozens more providing backup, including members of Motley Crue, Twisted Sister and W.A.S.P.

Distinct among all these musical charities of the time, “Stars” did its metal heritage proud by boasting an extended jaw-dropping guitar solo that collated fireworks of shredders like Yngwie Malmsteen, Dokken’s George Lynch, Craig Goldy, B.O.C.’s Buck Dharma Roeser, Twisted Sister’s Eddie Ojeda, Journey’s Neal Schon, Quiet Riot’s Carlos Cavazo, Night Ranger’s Brad Gillis and co-songwriter Campbell, who also contributed rhythm guitar parts, along with Iron Maiden’s Dave Murray and Adrian Smith, who flew in from their band’s massive World Slavery Tour to do their part with harmony parts.

Even Ted Nugent came down to sing backup — as did the members of spoof-metal band Spinal Tap to lend a few laughs to the otherwise dead serious circumstances.

Unfortunately, obtaining legal clearance for so many artists signed to so many different record labels proved a daunting task that would delay the music’s release for months. The Hear ’n Aid compilation LP finally arrived in stores in January 1986, packing recordings donated by major names such as Kiss, Rush, Motorhead, Accept, Y&T, Scorpions, the Jimi Hendrix estate and Dio.

By then, “Stars” had also been made available as both 7” and 12” singles (peaking at No. 26 in the U.K., No. 39 in the U.S.), and the entire historic event was eventually celebrated by a 48-minute documentary filled with interviews, outtakes and behind-the-scenes clips. And while some of those involved feared that the legal delays had diminished Hear ’n Aid’s impact, one could likewise argue that they also extended awareness for famine relief for a few more months, well into 1986.

In any case, the nearly $1 million raised by Hear ’n Aid speak for themselves, and the still-unmatched collection of heavy metal star power that came together during those two days in the name of a good cause.
