wall2wall Jazz Festival is proud to welcome The Siglo Section, Cardiff’s hottest young big

band, to this year’s festival lineup.

Founded in 2019 by dynamic duo Matt Lush and Loz Collier, The Collective has quickly

established itself as one of South Wales’s premier jazz ensembles – bringing a bold, youthful

energy to the big band tradition.

This 18-piece powerhouse features the classic big band formation – saxes, trumpets,

trombones and a full rhythm section. Their repertoire blends swing-era classics with modern

funk, innovative arrangements and original works from within the band.

This vibrant ensemble showcases South Wales’ top emerging talent and features the

standout vocalist Kat Rees. Kat is a Welsh bilingual jazz singer celebrated for her soulful

voice and innovative blend of traditional and contemporary jazz. Featured on BBC Radio

Cymru and BBC Radio3, she made history with The Siglo Section by releasing the first

original Welsh-language big band jazz EP. Praised as the “Welsh Ella Fitzgerald,” Kat

continues to captivate audiences both live and on air.

More than just a band, The Siglo Section is a vibrant musical community – a hub for

creativity, collaboration and high-calibre live performance. Whether they’re channelling the

golden age of jazz or pushing boundaries with contemporary sounds, their performances are

electrifying, fresh and not to be missed.

Join us at wall2wall Saturday to experience the energy, skill, and spirit of the next generation

of big band jazz.
