In 1979, following the release of the EP Jorge Morreu, the late radio broadcaster António Sérgio described UHF’s sound as Portuguese underground. He recognised there a new musical and literary language emerging from the outskirts of the south bank of the Tagus. Hard-edged in its depiction of reality and raw in its means. Forty-seven years on from that first record, the “locomotive from Almada”, as some called them at the time, bring their UNDERGROUND-UHF concert to Casa da Música, where they are performing for the ninth consecutive year. The band’s repertoire for this one-night experience is “almost untouched”, and no requests are allowed. The choice has been made and is non-negotiable: “22 songs emerging from the lair that the hits have concealed.”
