A Musa is a time machine, a journey through the history of urban culture of the second half of the 20th century, focused on the "foundations of culture, the pillars of (hip-hop) movement", according to Maze's own words. Its optical narrative is based on a matrix with the shape of a reference manual, or of a memory album where we encounter many iconic names of music, such as Notorious Big or the collective Wu-Tang Clan, as well as of cinema, visual arts or grafitti forms of creative expression which are deeply connected with the emergence of the urban metropolis and post-industrial society.
