The video above doesn't really give you "the story f his life" as it says. But what U can say about it is he's the son of Beatriz Márquez and Pepe Maza, Beatriz being more famous than Pepe but he was also a singer. As they show he started singing when he was quite young, 8 in that video. His mother was married t David Calzado for a while which made him Calzado's step-son. I'm not sure the exact age but he was about 15 or 16 when he started singing with CH. And I know that by the time he was 18 he had a drug problem.
The suspension of the Charanga Habanaera after the concert in August 1997 was blamed on his "striptease" up on the scaffolding of the stage, although I think that wasn't the only reason. I think there were a lot of things about the concert that pissed off the powers that be. During the suspension the CH broke up. Danny Lozada stared his band with Juan Carlos Gonzales and shortly thereafter everyone else except for Michel left and created Charanga Forever. Michel stayed with David for a while but then went to CF for a short while (because he was kicked out by David? I don't know).
Anyway he left CF and did some solo stuff for a while. Released a couple of good CDs with Envidia. Also sang as a guest with Revé a few times. And then eventually headed off to Peru, which I felt would be a bad move for him because of his addiction problem Obviously I was right (as I almost always am

)
IMO Michel has the most powerful voice among all the young Cuban singers. He has a huge range and unlike most singers whose voices are weaker at the lower edge of their range, his is just as strong wherever he is singing. So really an amazing voice. A talent for ballads maybe from growing up with his mother's influence. Very charismatic on stage.
It's sad to see where he is today. One of the "bright stars" that I expected a lot from who just faded away despite all his talent becasue of his drug addiction.
