In 1998, he participated in the Ezkerraldea Plastika group exhibition, which toured the Left Bank. In the catalogue published for the occasion, Vidal de Nicol s describes Gallo Bidegain's painting as follows:
"In this artist's paintings, each city—and he has evoked many for us—has its own atmosphere, its own intimate temperature. Sometimes there are sky-high skies rising above the urban landscape, stormy skies that give us immediate information about what the artist wants to tell us about it. Other times, it is only the colors that take us to those rendezvous with reverie, with poetic invention: those atmospheres I have seen in some of his paintings where the jaundiced yellows or the melancholic pinkish tones speak to us of the quality of the cities evoked, of their most hidden pathologies or their healthy future dreams."
