He was followed during the trip by filmmaker Lorenzo Fonda, who documented the experience and turned it into the documentary film Megunica, for which Blu created a series of animated segments using digital software.

In 2009, Blu started his umpteenth tour around South America, visiting Bogotá for the festival "Memoria Canalla," then Montevideo, Uruguay, back to Buenos Aires, and, for the first time, Lima, Peru, where he painted the entire façade of an historical building in the central Avenida Arenales.

[8] In 2007, Santa's Ghetto,[9] a London-based art collective that organises annual happenings of painting performances and print trade fairs, invited Blu to a festival that took place in the West Bank.

Blu was part of a group of artists, including Banksy, Mark Jenkins, Ron English, Swoon, and Faile who painted on the wall around Bethlehem that separates the West Bank from Israel.

First suggested in 1923 as one possibility for the expansion of Vienna's harbour facilities, Albern was selected for realisation by the German Reich Ministry of Transport (Reichsverkehrsministerium) in 1939, a year after the "Anschluss" of Austria to Nazi Germany.

The project was to serve as a logistic node of a future geo- and biopolitical order, designated for the transshipment of grain from the annexed or economically colonized regions of eastern and south-eastern Europe to the heartlands of the German Reich.

Realized on one of the granaries, Blu's mural called upon the overdue historical and social commemoration of the place's charged history and the unknown fates of the forced labourers who built it.

[15] The following year, the Tate Modern[16] presented an exhibition on the phenomenon of street art and invited Blu,[17] along with JR,[18] Faile, Sixeart, and Os Gêmeos[19] e Nunca, to paint its entire main façade.

In consultation with Blu, the two murals at Cuvrystraße were covered with black paint in 2014 by a group of people as a sign of discontent with the city's urban development policies in the area.

In Bologna his work is visible at XM24, TPO, Livello 57, Crash; in Rome at Forte Prenestino and Collatino; in Milan at Cox 18 and Leoncavallo and in Pisa at Cantiere San Bernardo.
