Blu is the pseudonym of an Italian artist who conceals his real identity. He was born in Senigallia. He lives in Bologna and has been active in street art since 1999. His early career involved the practice of shared artistic actions. Artists such as Dem, Sweza, Run and, above all, Ericailcane, were his companions during nocturnal raids where an anonymous creative participation overcame the need of signing their pieces. Also, during those years, Blu started experimenting with digital animation, and he created short interactive video clips that were used as a visual contribution to the live musical performances of the collective OK NO. The collaboration with Ericailcane had its best results from 2003 to 2006. The two personalities complemented each other; while Blu was painting his characteristic human figures Ericailcane made his typical animals. The two artists, friends in real life, continue to work together, although less often. Starting in 2004, some art galleries noticed Blu's artistic value and invited him to take part in both one-man and collective shows. Yet Blu, throughout his entire youthful career, attempted to limit his presence within the official art world, preferring other kinds of territories. Since his major pieces outside of his videos have been immovable murals, the survey below of Blu's work is geographical rather than chronological.
