This week's new events

Art Car Boot Fair , London Time to clear some space on the mantelpiece/lounge wall/back of the loo door: the annual Vauxhall Art Car Boot Fair rolls into London's Brick Lane next Saturday. In the past six years its down-to-earth premise – artists sell their own work from the backs of their motors – has seen a roster of art stars pitching up. This year Sir Peter Blake, Bob and Roberta Smith, Ian Monroe, Pam Hogg and Gavin Turk are among those returning. There's plenty to do besides the bargain hunting, too. Martin Creed and his band will be performing their own brand of energetic minimal art-rock, while the car park features a collaboration between Billy Childish and Jimmy Cauty. Brick Lane, E1, Sun Skye Sherwin BASS Festival , Birmingham The fifth outing of this festival of black arts and music looks a peach. Spearheading the visual arts strand is an awesome collection of protest and propaganda pictures from the past 20 years at The Custard Factory, while attractions on the musical side include London roots reggae stalwarts Jah Shaka Sound System (25 Jun), plus Beyond The Ballroom (13 Jun), a look at jazz dance history taking in archive footage from Camden's Electric Ballroom, a Q&A with Acid Jazz's Snowboy and a demonstration from jazzstepper Irven Lewis. This week, look out for Desert Boy (10 to 12 Jun), a musical theatre piece from Mojisola Adebayo taking in slave songs, hip-hop, and Malian music. Various venues, to 26 Jun Stuart Goodwin Camden Green Fair & Bikefest , London This huge volunteer-run eco event reaches its 18th birthday, and a new Village Fete offering wellie-wanging, tug-o-war and "free-range organic egg-and-spoon races" means there's still scope for wacky fun despite its serious, adult message − that green living is for life. Young environmentalists can try storytelling, wigwam-building and puppetry while grown-up greenies learn nappy-making, bee-keeping and rain-harvesting. There's also a fashion zone and Bike Fest. Regent's Park, NW1, Sun Colette Bernhardt Out & about HowTheLightGetsIn , Hay-on-Wye, Sat & Sun The philosophy and music festival wraps up with a weekend featuring King Creosote playing a Swn-curated stage and Zygmunt Bauman on utopias and dystopias.
