It was an unexpected treat to catch Israeli band the Apples at the end of their storming set at Cargo. With four horns, bass, drums and turntables, their oddly effective mix of instrumental hip-hop and soul-jazz got the crowd dancing and jumping, while giving listeners plenty to latch on to. The hard-edged, brassy sound was pushed along by drummer Yoni Halevy, and they closed with a cracking cover of Rage Against the Machine's Killing in the Name.

San Fransciscan post-punk legends Tuxedomoon are celebrating their 30th anniversary with a box set and the album Vapour Trails. For the fans, they delivered the obligatory, thumping grooves - but agnostics were equally impressed. The four musicians have matured into a phase of accelerated creativity, with Steven Brown's splintery piano and astringent sax, and Blaine L Reininger's powerful violin, craggy voice and deep, twanging guitar. Ponytailed bassist Peter Principle plays the band's repetitive riffs perfectly.

Belgian trumpeter Luc van Lieshout was back the next day to play with the Flat Earth Society, a tight 15-piece band led by clarinettist and composer Peter Vermeersch, late of X-Legged Sally. Two brilliant sets confirmed how accomplished they are, twisting rapidly from theatrical bombast to tenderness, collective improv, mad movie-chase music and back to swinging anthems such as Gulls & Buoys and, er, Anthem 2004. Wet is Wet presented jazz as envisaged by Goebbels. Vermeersch grins impishly, like a young Daniel Libeskind, as he directs his close-knit ensemble. He is a monster talent, with an outrageously original band.
