£7 on the door.Presented by Short Waves & Hey Boy MusicLeo Walrus is a Southend-born, South East London-based singer-songwriter blending indie folk, neo-soul, dream-pop and alternative music.

Described as “tender, measured but heartful,” his music draws on influences from Marvin Gaye and Curtis Mayfield to Steve Lacy and King Krule.

Leo will preview brand-new material recorded at Studio 13, the London studio founded by Damon Albarn, as part of his forthcoming work with Hey Boy Music.Founded in 2026, Hey Boy is rooted in the musical and cultural heritage of London.

Its founder grew up in a London home filled with records ranging from Suicide, The Clash and Peter Tosh, absorbing a city where underground culture and mainstream music constantly collided.

His career later took him to Spain, where he co-founded Mushroom Pillow in 2001.

Hey Boy carries that independent spirit forward, championing artists with a strong point of view, creative freedom and international ambition.Underdown brings a theatrical, piano-and-sax-driven take on rock ’n’ roll, combining classic songwriting influences with a contemporary edge.Celeste Madden is a South London singer-songwriter whose intimate, offbeat songs move between humour, vulnerability and melancholy, creating music that is both emotionally honest and distinctly her own.Three individual voices, one night of new and independent music at Jaguar Shoes.Presented by Short Waves & Hey Boy MusicThis is an 18+ event
