Three things set SUBJAM apart. First, the lineup goes deep into UK garage and old skool with original artists performing live PAs of the records that defined the era, including 'Sweet Like Chocolate', 'I'm Gonna Get You', 'Red Alert' and 'Liferide'. Second, four stages across one outdoor site means a single ticket covers house, funky house, UK garage, old skool and club classics rather than a single sub-genre. Third, the family-friendly daytime format makes it a different proposition to typical late-night urban garage events. Learn more at www.subjam.co.uk.
