Mariano Tester Alonso belongs to the artist collective rundontwalk, together with stencil artist Fede Minuchín. A self-taught and collectively trained artist, his career began in the late 1990’s, developing within the local music scene before taking to the streets.
Tester’s compositions are a riot of abstract and popular phrases, stamps and lettersets combined with hand-drawn forms. Heavily influenced by the DIY attitude of the Buenos Aires punk rock scene, Tester creates elaborate works using analogue processes and a range of materials including aerosol, ink and acrylic paint.
In 2006 he was one of a group of 6 street artists to launch Hollywood in Cambodia, an artist-run street art gallery in Buenos Aires. In 2014 he helped create Club Albarellos, an art studio and gallery en El Tigre, Buenos Aires.
