I think the third album of Abe Rábade Trío (the fourth if we count the GHU! Project Vol.1) is a maturity album. I understand Babel de sons and Simetrías as great sets of themes, performed with virtuosity, heart and the Trío style.
Playing on light is a set of seven themes that express the feelings (sensuality, introspection, despondency, helplessness, violence, protection and enlightenment) of Abe about seven photos (included in the booklet). But it’s more than a set of seven themes. This is a perfect, one work in seven times. When I hear each piece of the album I feel I’m hearing different sides of an heptaedron, even when Abe caught us with a non-accoustic theme
