Trombone quartet in Sainsbury's New Cross Photo: Sampler Facebook profile

Fans of spontaneous live music will be pleased to know that two guerrilla gigs are taking place in Brockley this Saturday, as part of the month-long, Lewisham-based Sampler festival.

Chen Ying Chuang will be making appearances at the Brockley Jack theatre and Mr Lawrence Wine Bar on Brockley Road between 6pm and 9.30pm, showcasing a range of playing styles on the lute. His performance is the last in a short series of guerrilla gigs that were put on as part of Sampler but kept firmly off the official programme. So far Lewisham shopping centre has seen a modern dance routine, Deptford Market a flute beatboxer and Sainsbury’s in New Cross has hosted a trombone quartet.

Sampler runs until November 28, across a selection of intimate and arty venues across the borough. It’s a festival that, in its own words, is “the modern way to enjoy classical music” splicing “modern, contemporary and crossover” styles from Tchaikovsky to Grime.

Events taking place this week start on Thursday evening with Synthesis at the Albany, a modernist club night featuring an audio-visual performance by Minima. Friday sees Lunch and Listen at Blackheath Halls, with the Barbican Trio at the same venue on Sunday. The festival then resumes on November 18 with Being Dufay, a contemporary sound world creation by composer Ambrose Field and singer John Potter.
