Gulbenkian's Jazz em Agosto Closes Its 42nd Edition with an L.A. Collective in the Garden

Lisbon's longest-running summer jazz institution reaches its finale on Sunday, 9 August, as the Los Angeles collective SML close the 42nd edition of Jazz em Agosto (Jazz in August) at the Fundação Calouste Gulbenkian (Calouste Gulbenkian Foundation).

The festival unfolds each night in the foundation's Anfiteatro ao Ar Livre (open-air amphitheatre), tucked into the Gulbenkian garden — a setting that has defined the event for decades, trading the concert hall for warm evenings under the trees. It is a format that draws a devoted local following and a steady trickle of visiting jazz fans each August.

SML, who record for the influential Chicago label International Anthem, bring a restless, improvisational ethos to the closing slot. "We don't want our music to solidify into one sound," the band said of an approach that resists settling into a single style — a fitting note on which to end a programme built around risk and reinvention.

This year's line-up leaned into that spirit. The edition opened with the German pianist Joachim Kühn and featured the Chicago Underground Duo, threading together European and American strands of the avant-garde.

One of the standout nights came on 3 August, when L.U.M.E. — the Lisbon Underground Music Ensemble, a 15-strong big band conceived by the composer and pianist Marco Barroso — delivered the first sold-out concert of the 2026 programme. The set opened not with a horn blast but with an acousmatic field recording of the Gulbenkian garden's own soundscape — ducks, birdsong and a passing plane — before the live instruments took over, dissolving the line between the venue and the music played in it.

The ensemble also revisited "Freestyle Boogie", a piece from its album Xabregas 10 that was itself recorded live at Jazz em Agosto back in 2014 — a reminder of how deeply the festival is woven into the recent history of Portuguese jazz.

Founded in the 1980s, Jazz em Agosto has become one of Europe's more adventurous festivals of its kind, favouring experimental and free-jazz programming over crowd-pleasing headliners. That editorial nerve, and the intimacy of the garden amphitheatre, are what keep audiences returning summer after summer.

With SML's set on Sunday, the 42nd edition draws to a close — and the Gulbenkian garden falls quiet until next August.
