Wednesday, September 28 and Sunday, October 2.Those are the days when DIO: Dreamers Never Die, the documentary about the small voice giant, will be screened.It is an exploration of Ronnie James Dio's career with his early bands, his days in Elf and Ritchie Blackmore's Rainbow, to replacing Ozzy Osbourne in Black Sabbath and finally cementing his status as a legendary metal icon with his own band, IT GAVE.The film incorporates never-before-seen footage, personal photos and scenes with his closest friends, family and colleagues, including Wendy Dio, Tony Iommi, Geezer Butler, Glenn Hughes, Vinny Appice, Lita Ford, Rob Halford, Sebastian Bach, Eddie Trunk and JackBlack.In addition to the film itself, there will be a selection of shots that weren't left behind after editing and will only be shown at these screenings.This to create an exclusive experience for fans.It will be like having some of the post-credits scenes that have become popular in superhero movies.The respective press release says that “Ronnie James Dio, who died of stomach cancer in 2010, reigns as one of the most influential rock artists and one of the greatest vocalists of all time.With an illustrious recording career spanning from the 1950s to the 2000s, the documentary follows his journey from sideman to singer, songwriter and leader of not one, but three of the most recognizable rock bands in the world: Rainbow , Black Sabbath and DIO”.And beware, he not only had to replace Ozzy but also return to Black Sabbath, to the highest quality standards.There are even more frivolous elements that are part of its history, such as popularizing the gesture of the horned hand, also called "devil's horns", an inescapable synonym of hard rock and heavy metal (much to the dismay of the Kardashians and all that harmful fauna). .Now, is a documentary about Dio important?Of course it does, because beyond being in Rainbow (think of “Stargazer” and the enormous range of nuances of his voice), in Black Sabbath (same thing but that it is, for example, “The Sign of the Southern Cross ”) and DIO (how about “And all the Fools Sailed Away”), Ronnie was and is an inspiration to hundreds of musicians from all subgenres of metal.With the exception of Vivian Campbell, it is difficult to find someone who speaks ill of him, and not only that, it is almost unheard of to find someone who does not mention him with reverence.Every genre needs its heroes, and while beans are simmering everywhere and in metal there are examples of enormous talent leading sleazy lives, Dio was generally a decent human being, far removed from scandals, run-ins with the law, and exaggerated myths about rockstarism.Simply a musician dedicated to his art, an excellent composer and lyricist, elements that he never hurts to rescue.Many complain that it is Wendy Dio who produces the documentary, they say that she does it for money and, once again, instead of enjoying a document like this, more than one belittles it for ridiculous reasons.It is a job that could put one of the greatest singers in history in a more desirable place.Others sold more, but none sang like him.
