The recent cloudy and rainy weather may have been misleading, but summer has arrived, and along with it a recently introduced multi-day music festival, Summer in the City, now set to go in Athens. The event, scheduled to run for 13 consecutive nights at Club 22, opens tomorrow evening with scores of local bands and DJs on its agenda. There could be good things waiting in store. Over 50 acts – many of them unfamiliar and representing various contemporary styles – will appear in nightly sets comprising four or five bands. A headliner will be Sigmatropic, the Athens-based act that recently gained wider exposure both here and abroad following the release of «Sixteen Haiku And Other Stories.» The project will also feature esteemed foreign musicians such as Robert Wyatt, Carla Torgerson (The Walkabouts), Lee Ranaldo (Sonic Youth), Howe Gelb (Giant Sand), James Sclavunos (Nick Cave’s Bad Seeds, Vanity Set), and Steve Wynn. But the festival’s other acts have yet to achieve any breakouts. Some of the newer bands will use the occasion to launch and promote new albums, some of them debut works. All 13 nights of the festival have been thematically divided. Tomorrow’s opening night features four bands – 700 Machines, Ducky Boys, Teardrops, and Hipsters – and is entitled «It’s Only Rock’n’Roll.» Thursday is «Metal» night, Saturday travels to «Planet Hip-Hop,» Sunday you can «Dance With Me,» and next Tuesday asks: «What is Pop?» Summer In The City, the second to be held, was launched last July at another venue, House of Art, in the active downtown district of Psyrri. Summer in the City, tomorrow through June 13, at Club 22 (22 Vouliagmenis Ave). Starts at 9.30 p.m. nightly. Admission 8 euros. For further information tel 210.345.5241.
