Trust is the secret ingredient that makes an event more than just a night out. Whether it’s a party or a festival, knowing that the people behind it are genuine music devotees changes everything. Mostra Festival has built that trust over time, and for a good reason—they’re music nerds through and through. For this week's mix on "Delayed with..." series, one of Mostra’s core members steps up to the decks at Barcelona’s beloved Laut, debuting a new alias: Corsair, the latest incarnation of Josh Hoppen.

This mix is a dispatch from the front lines of ExtraMostra, an international celebration of Mostra’s ethos that recently touched down on home turf in Barcelona featuring Josh Hoppen aka Corsair, Muted, and Memory Palace. Corsair brought the raw energy of UK breaks straight to a dancefloor that knew exactly what it wanted. And it’s clear from the first beat that Corsair knows how to deliver.
The set showcases Hoppen’s encyclopedic music knowledge in a natural and unforced way. It’s all about tension and release, powered by an ever-evolving array of broken grooves. If you’re the type who likes to label things, you’ll catch hints of halftime, jungle, drum and bass, dub, techno and even a touch of trance—genres that weave in and out like old friends at a reunion. But Corsair’s magic lies in how he blends them into a seamless journey, always keeping the dancefloor on its toes.

This mix celebrates bass in all its glorious forms, propelling the crowd into a state of relentless energy. It’s the kind of low-end therapy that shakes you to the core—literally. Sharp percussions slice through the air, riding atop liquid synth lines, while the grooves shift and adapt like a chameleon changing colors under the strobe lights.
No excess, no pretense—just a set that hits hard and stays with you. Moments like this show why Mostra keeps us coming back.
Play it loud. Let Corsair guide you through the heavy basslines and restless rhythms. Well done, Josh. Here’s to whatever comes next. Long live Corsair.

Founded in Brooklyn and run by a team of music producers, DJs, and perpetual music addicts.

Growing up in late 90s and early 00s Dublin, Jay Galligan’s surefire instinct for catching a mood and manipulating grooves is no happy accident.
A talented musician in his own right, he evolved from guitar and grunge fuelled Indie shoegaze bands to a purveyor of full throttle Techno as waves of new mutant music ushered in a new era.
As a whole generation of ‘My Bloody Valentine’ fans started to listen to Detroit Techno. He found himself in the thick of Dublin’s movement: holding a residency at the legendary club ‘Electric City’ and his own night ‘Test’ for over 10 years.
No stranger to the dynamics of the dancefloor – he has played many times alongside the likes of Dave Clarke, Jeff Mills, Robert Hood, Ben Klock, Surgeon, Dopplereffekt & Regis. At a time when the Irish Techno scene was incredibly organic with a strong community vibe.
These days, Bristol is his home where he has turned his musical attention to producing finely crafted radio shows.

Rochelle is a Barcelona based artist [via Houston -> New York] that has been a dynamic force in the community for over 15 years. With a deep-rooted passion for electro, breaks, acid, garage, and minimal, her eclectic sound defies categorization, blending genres seamlessly and showcasing her versatility at every opportunity, a true chameleon of her craft. Guided by a love for music that surprises and captivates, she consistently delivers fresh, unexpected sounds, offering her audience something new with every appearance.
