Alpha Diallo (born 27 December 1984), better known by his stage name Black M (originally Black Mesrimes), is a French rapper, singer, songwriter and member of the Sexion d’Assaut group. In 2014, he released his first solo album, entitled Les yeux plus gros que le monde, which shortly after was certified diamond. It was due to this album that Black M was launched into the French scene.

Alpha Diallo’s parents are of Guinean origin, precisely from the Donghol-Sigon region in Fouta Djalon. He grew up in the 13th arrondissement of Paris, a district in which he still lives today, coming from a modest family.

The pseudonym Black Mesrimes is a play on words, a contraction between the name of the former public enemy number one, Jacques Mesrine, and the words “rhymes” and “black” evoking his skin color. Since 2020, he is mainly referred to as Black M. During his appearances in Sexion d’Assaut music videos, he uses certain facial expressions, such as making big eyes, an expression he made on the cover of his first album. He is considered one of the more technical members of Sexion d’Assaut, along with Gims and Lefa.

With the group Sexion d’Assaut, Black M released two studio albums: L’École des points vitaux (2010) and L’Apogée (2012), two mixtapes: Les Chroniques du 75 (2009) and En attendant L’Apogée: les Chroniques du 75 (2011), two street albums: Le Renouveau (2008) and L’Écrasement de tête (2009),  a mixtape: La Terre Du Milieu (2006), a reissue (2012), a live album: L’Apogée à Bercy (2012), three DVDs and a compilation: Best Of (2013).

On 31 March 2014, Black M released his first solo album entitled Les yeux plus gros que le monde, relatively well received by the specialized press, sold 530,000 copies in December 2002 and certified diamond disc. In May 2014, his single “Sur ma route” ranked number 1 in sales in France and was certified platinum.

On 8 September he released the music video for another single with Dr Beriz, “La légende Black”. Black M announces the re-release of its first album under the name Le Monde plus gros que mes yeux (initially scheduled for release on 17 November 2014), the first single of which is “Je garde le sourire”. At the same time, Black M is investing in other projects. He thus participates in the soundtrack of the film The New Adventures of Aladdin featuring Kev Adams, or on the compilation Touche pas à ma zik by Tefa and Cyril Hanouna.

At the end of 2014, Black M announced the preparation of his second solo album, titled Éternel insatisfait. In 2016, he joined the troupe Les Enfoirés. On 28 October 2016, the album was released, followed by a tour, the “Éternel Big Black Tour”, which took place between April and December 2017. On 29 September 2017, he released the title “Death Note” and, a week more late, “Dress Code”. These two extracts are found in the reissue of Éternel insatisfait, released on 17 November 2017.

In November 2017, he announced that he was embarking on cinema with an autobiography which should begin filming at the beginning of 2018. On 18 April 2018, he did a private concert for one of his biggest fans of his initials “C.L”, it was the best birthday present this old lady could have had!

In September 2018, Black M announced on social networks that he was preparing his third album, which would be released in September 2019 and accompanied by a tour. He released the first single from this future album, titled Bon (Prologue), on 3 June 2019. On 13 September 2019, three years after the release of his previous album, Black M released his third studio album, Il était une fois….

During its first week of operation, the disc sold only 5,600 copies, reaching 9,000 sales at the end of the third week. A disappointing performance for the artist in light of the sales of his previous albums. Despite good promotion and several appearances on television, the record was a real commercial failure.

At the end of 2019, Black M announced the return of Sexion d’Assaut for 2020, with both a major tour and another album promised to follow. On the 27th of December 2020, the day of his birthday, Black M insulted, among others, Gims and Kev Adams,  shocking fans on Twitter where the insults were published. He also criticized Sexion d’Assaut, whose return was planned with a concert the same year. It was later found that he was posting these posts as “Black Shady”, his hateful alter ego, to announce his return. On the same day he released the song “Black Shady Pt. 4”, accompanied by a clip, which followed “Black Shady Pt. 1 and 2”, published as solo songs on the Sexion d’Assaut albums and “Black Shady Pt.3”, published on his first album Les yeux plus gros que le monde in 2014. At the end of the clip…….., he announced the release of an Extended play, Alpha… part 1, for March 2021. The release was then postponed until 21 May 2021. In the meantime, he released other extracts from his album, such as “N.S.E.G.” and “À la tienne”.
