Even as a child she excelled through her special literary and artistic talent, that allowed her to attend the most elite boarding schools in Italy (among others the renowned 'Collegio delle Fanciulle' at Palazzo Archinto in Milan). During grammar school, at the age of 17, she was co-founder of the Italian Akróama TLS Contemporary Art Theater, which quickly established itself internationally, and conquered the most renowned international festivals (Spoleto, Edinburgh, Santarcangelo, etc.).

'... The violent emotion, open sensuality overwhelmed me with its purity… making Peter Brook's anthropological experiments seem silly and unconvincing in comparison...' (Bonnie Marranca, Performing Arts, New York)

Her solo performances in Vienna collect an exceptionally high level of enthusiasm from both audience and critics.

'... One of the most fascinating Italian artists of movement... In dance, without words, always indicating her conviction: I am art.' Konrad Kramar (Kronen Zeitung).

'... She's been described as a phenomenal expressive artist from Sardinia, as ‘the most fascinating artist of movement', whose goal of work is an 'earthquake': Assunta Spissu. Her art: dance theatre of maximum consequence...' (Kurier)

'... The preparation of the actor, the training of body and voice are at the center, show the spectator how much intensity, concentration and discipline there is in these scenes that hover between pantomime, dance and clowning...' (Die Presse)

'.... When Assunta Spissu performed her solo program to the public it literally took their breath away. The critics did not spare in their hymns of praise ...'

'Presence, mastery of the body, concentration, energy and creativity of the actor are taught in drama classes by Assunta Spissu in a way that leads to a synthesis of expressiveness and sincerity…' (Wiener Zeitung)

In the field of visual arts she has created, through works of painted-over photography, the new artistic movement 'mytho-futuristic-expressionism' and by sculpture-relievo, the current 'futuristic-memorial-art'.

Her 'erotic self-portraits' of the years 2003-2006 give further testimony of her exceptional artistic and physical self-formation, which Heinz Sichrovsky rightly described as 'the unimaginably perfect functioning of a body and a will...'

From 2000 until 2008, she also wrote the books 'Amore sono le sei', 'Love? Three stories of ordinary extraordinary love.' and 'The artist and the search for the ideal man'. These are love stories which aim at clear and positive societal reforms.

In her Music-Theater performances she created vocal and musical compositions of expressive, deep intensity and collections of poetry of high artistic level.
