Moisès Villèlia was a builder of aerial forms and one of the greatest exponents of the avant-garde movement that would break with informalism to enter the conceptual current. In 1954 he made his first individual exhibition at the Municipal Museum of Mataró in which he presented some reliefs that combined the influences of modernism and Eastern philosophy, which since his teenage readings was a constant in his life. Joan Brossa visited this exhibition and a great friendship was established between them. Through Brossa he would meet the Dau al Set group and Joan Prats.
In 1974 the Polígrafa Publishing House dedicated a monograph to him, and in 1979 he showed his works in cane at the Dreistel Gallery in Cologne and at the Martha Jackson Gallery in New York. The Joan Miró Foundation of Barcelona and the Generalitat de Catalunya organized a retrospective exhibition in 1983 that reviewed the different stages of their production. In 1989 he wrote a play, "The Artist", which has been considered as his artistic testament. In 1992, on the occasion of the Universal Exhibition of Seville, the Pavilion of Catalonia presented an exhibition of the work of Moisès Villèlia, with a series of large format mobiles. In 1999, the IVAM, Institut Valencià d'Art Modern, in Valencia dedicated an anthological exhibition.
