They weren't a family of igawen (griots), though the music was an important part of their family life. Her father had a good voice but the artistic gift came from her mothers' side. Her aunt Zaina was quite known as a singer and dancer, her uncle Bushad as a poet and her mother used to sing on birthday celebrations, weddings, in Ramadan or simply if a friend they hadn't seen for a long time came to visit them. Among her brothers there is Boika Hassan, a good guitar player and Mohamed Salem, a poet.
Already very young, when the Sahara still belonged to Spain, Mariem used to sing in small private parties and participated in the clandestine meetings, where the saharaui people rendered their musical culture. It seemed a very natural thing to do. Although two of her brothers were in the Spanish army, the family and their surroundings were longing for the independence of their country, like all the former African colonies did in these years. Mariem was 17 years old when the "Marcha Verde" (Green March) took place. Her two brothers who were in the army had cars and so were able to bring the family to the enclave of Mjeriz, next to Tifariti, first stage of the exodus. From there they proceeded via Argelia to a place in the inhospitable Hamada. Their camp is known as Smara, in remembrance of the town the biggest part of its inhabitants had to leave behind. Mariem Hassan has lived there for 26 years. This is the place where her five children were born. Today she lives with her husband and children in Barcelona.

The four big camps are named after the four wilayas - provinces - of the western Sahara - Smara, El Aaiun, Auserd and Dajla - and organized in the same way. Each wilaya is divided in dairas - districts - and those are divided in quarters. In each of these localities a group of musicians takes charge of maintaining the traditional culture.
The "Frente Polisario" realized the necessity of having a permanent group of musicians with clear political ideas that could help with the international promotion of their concerns. Those were the years when Spain had numerous politic songwriters, the "Nueva Trova Cubana" had her best moments and people still were listening to the songs of Victor Jara and Quilapayún.
That's how the group "El Hafed" came into life, later - after the founder and first secretary of the "Frente Poliario" had fallen - named "Martir el Uali Mustafa Sayed", better known as "El Uali". Mariem immediately became part of the group and travelled with them to various countries to take part in cultural events of a high political impact that during the war with Morocco often were boycotted by Moroccan activists and functionaries. "El Uali" recorded four or five albums in different countries, always with the help of the solidarity committee concerned. Among these albums "Polisario Vencerá" stands out, which was produced by Mohamed Tami, Sahawraui Minister of Education from the late 70s to the mid 80s. Originally, it was published by Guimbarda in 1982, then again in 1998 by Nubenegra. Mariem Hassan like many of the other women that participated in "El Uali" took part in recordings or tours whenever she was able to, i.e., if she was not pregnant or had to care for her children. She is on the album that was recorded in Holland in 1980, but which never was published, and on the one that was published in France in 1989 but didn't get far either, because twhe tour that was being prepared to substitute the launching of the album had to be suspended.

Therefore it wasn't until 1998 when we finally could enjoy Mariem's voice in some songs of the album A pesar de las heridas. Among these the Canción de la Intifada stands out and since then has been one of the most impressive songs on the tours of the group Leyoad. After four years of intense work with Nubenegra, Leyoad has grown strong thanks to two of the most important persons in Saharaui music who always stayed with the group, Mariem Hassan herself and Nayim Alal.

Lately Mariem Hassan has focused more on writing music. By summer 2000 Nubenegra proposed Leyoad to record an new album and Mariem contributed beautiful songs like Sahara neb gija or Yasar geidu. Mariem Hassan has started a solo career which began with the album Mariem Hassan con Leyoad With the actual quartet she is apt to recreate the whole universe of the haul. In the intimacy of her small group her figure is growing immensely large and leaves us speechless with the intensity of her voice.
2003 she performed at the Jazzfestival in Moers, in theatres in Ermua and Alsasua and also in France in Bordeaux, Gonfreville and Le Mans.

The critics unanimously recognized her as the best voice of the Western Sahara, a fact which Mariem Hassan proved once again with the launching of the album Medej in May 2004. That same year she did a Europe tour participating in festivals like the
Fórum de las Culturas, Barcelona, AfroPfingsten, Winterthur, Africa Festival, Würzburg, Liederflut, Leipzig, Les Escales, France, Etno Soi, Helsinki, Festival Vía Magna, Madrid, Artistas en ruta (Salamanca, Madrid, Huesca) doing concerts in Espace Senghor, Brussels, Antwerpen and Luxemburg, Moods, Zurich, completing the year with concerts in Spain in Alicante, Oviedo, León, Alcoi, Gijón, Barcelona, Gracia, Santander, Guadalajara, Granada, Almonestar la Real, Elenco, Ciudad Real, Bilbao, Blanes, Tres Cantos.

2005, from the 7th to the 18th of March Mariem was invited by the governmental youth institute of Belgium for workshops and concerts.

21st of March, back in Spain, she got the diagnosis of a cancer and she was operated next day. After an absence of six months, Mariem Hassan is back to present her new release, Deseos.

It is her very personal solo album under the musical direction and guitar of late Baba Salama, with her brother Boika on guitar too and the push of the percussionist Fatta. Three of the best musicians coming out of the refugee camps of Tinduf.

The mutual understanding of the quartet can be appreciated in La tumchu anni, an impressive blues with taste of sand and sun and whose title don't desert me remembers that the situation of her occupied country is still unsettled. In Magat milkitna dulaa the two electric guitars let Mariem and her voice fly with unique energies into the four directions of the wind. And finally we can listen to the electric version of the Intifada, her best known song related to a rising in the occupied territories.

2005 at Mercat de Música Viva in Vic in September was the first station where Mariem presented her new album Deseos.

Unintentionally but unavoidable Mariem Hassan has become the representative voice for her people everywhere in the world.
