Espai Dual is the set of all the linear forms of a vector space on a body with an image of that same body. Apart from that, it is also a group from Almacelles made up of two people: Marc Cruz Pascual, from Cal Rosendo, and Eduard Morell Purdonés, the son of Rosa that works at the Guissona.

The concept that best defines their music is “dada”: taking something that don't makes sense and leaving it in a place where it doesn’t belong. The key to Espai Dual is to subjugate musical styles to the concepts of the songs: there is no group that can do country, j-rock, indiepop, metal and Ska like us. We recorded our first album in the attic of Marc’s house in a matter of a few months. Specifically, 36 months.

We have been making music together all our lives. We started by doing a tribute to Pink Floyd's The Wall, we continued with a covers band that came out of this first project, Pernil Salat, which played for 3 years at many Festes Majors in Catalonia, doing a tribute to Doctor Prats and La Pegatina. Currently, we are working on Espai Dual, doing a tribute to our own idiocy. One has a degree in musicology and the other in mathematics, and, with Pau Riba's permission, we have made the best fucking album in Catalonia: the LP "Espai Dual" was published in 2024 under the Protomaterial Records label.
Espai Dual also has some faithful collaborators, who are not Espai Dual: the Tècnicament Correctes, a backing band that accompanies us wherever we go.
