For some time Alessandra Celletti has been working on a new project dedicated to the history of a Native American heroine, Sacagewea, whose deeds are undisputed heritage of the North American culture, especially in the women studies.Born at the end of the 18th century in the tribe of Shoshone, when she was only 17, Sacagewea guided the Lewis and Clark expedition to the shores of the Pacific ocean and her help was fundamental to the success of the adventure. A young woman, alone with a baby on her shoulders, Sacagewea made the venture and the journey possible.Fascinated by the legendary figure of Sacagewea, Alessandra Celletti devoted to her history some compositions that will be published in the summer of 2010 by Al-Kemi lab in one of its alchemical boxes entitled "Sketches for Sacagewea", a sort of notebook of notes containing a CD with 5 tracks that anticipates the entire project, and a booklet which will include paintings inspired by the work of Alessandra Celletti, made by Leila Gabellino (Alessandra's mother and painter) and fragments of drawings by Alessandra as a child.
