When he started painting, he was concerned with expressing his historical time, without needing to give up on memories of the past or the desire to affirm the uncertainty of the future.

In 1969, along with Jordi Galí, Silvia Gubern and Àngel Jové, he created Primera mort, considered the first video art piece in Spain.

In the early 1970s he decided to abandon his artistic practice, which he resumed in 1979 with the series of cut-outs shown at the Fundació Joan Miró in 1988.

It was at that time that his large series began appearing: Epifanies i sofismes, Et in Arcadia Ego, Preposicions, Velletque videre, Sense penediment, Viatge d’hivern.

[4][5] His notable individual exhibitions include, among others: Antoni Llena (Fundació Joan Miró, Barcelona, 1988), La pintura como experiencia (Patio Herreriano - Museo de Arte Contemporáneo Español, Valladolid, 2005), SOS: senyals de fum des d’un subsòl (Centre d’Art Tecla Sala, l’Hospitalet, 2011) and Antoni Llena.
