The 1960s still continue to yield tasty fruit, and locals Rue '66 bring some fresh spoils to market. Rue '66, consisting of former members of Cat Heads, Hard Rain, It Thing, and Jammists, specialize in yé yé, a style popular in France, Spain, and Italy circa early and mid-1960s. Translating as "yeah, yeah," yé yé resulted from the clash of classy French pop (especially Serge Gainsbourg) with doo-wop, girl group, and rock 'n' roll, and Rue '66 captures its sleek, Mod-ish vibe with aplomb. (We got a taste of yé yé in the movie Moonrise Kingdom, via Suzy dancing to Françoise Hardy's "Le Temps de l'Amour.") The group headlines the free Fête de la Musique festival this weekend, with more than 10 bands and DJs, food, and drink.
