For all the acclaim and awards showered on Marion Cotillard and her lead role in the Edith Piaf biopic La Vie en Rose, it bears repeating that her performance was certifiably acting. In other words, it wasn’t Cotillard’s voice on the soundtrack, but rather that of Jil Aigrot
. A Cannes-based singer and actress herself, Aigrot couldn’t help but feel somewhat upstaged by Cotillard, quietly releasing a solo CD in the wake of the film’s success and sporadically touring. There are many Edith Piaf impersonators in the world, but few who can attain the emotional wallop of Piaf’s delivery. Aigrot is an exquisite exception; she performs Friday, April 1, at the Dance Palace (503 B St., Point Reyes Station; 8pm. $30–$32; 415.663.1075) and Saturday, April 2, at the Napa Valley Opera House (1030 Main St., Napa; 8pm; $35–$40; 707.226.7372).
