The ultra-hip Austin festival SXSW has this week returned to London, bringing with it headline-grabbing appearances from Michelle Obama and Mike Skinner, alongside the usual mix of tech debates, film premieres and new music. Last year’s inaugural London edition — featuring King Charles and Idris Elba — was a smash hit, and we’re delighted to be partnering with the festival for a second year. Across this week’s and next week’s issues, look out for our behind-the-scenes gossip, interviews and reviews from the front line of this cultural nexus.
