The seventh annual Decibelle Music and Culture Festival (formerly Estrojam) has scaled back a bit from the past few years, but its music lineup is still an impressive four days of indie rock, dance, electronica, funk, and hip-hop, Thursday through Sunday at several venues. The fest’s mission is to “create spaces where women can cultivate their talents in all creative areas,” and a portion of the proceeds will benefit Women & Children First bookstore and the Chicago Michfest Fan Fund, which helps cash-strapped concertgoers attend the annual Michigan Womyn’s Music Festival. Highlights of Decibelle’s music programming include French electro-pop chanteuse Emilie Simon on Thursday (9 PM, Berlin, 954 W. Belmont); soul-pop-funk-rock singer and bassist Meshell Ndegeocello on Friday (7 and 10 PM, Old Town School of Folk Music, 4544 N. Lincoln); a DJ set from JD Samson of Men and Le Tigre, also on Friday (10 PM, Berlin); the Decibelle Music Lounge on Saturday, with indie singer-songwriters like Anomie Belle, Chelsea Z, and Nive Nielsen (7 PM, Heartland Cafe, 7000 N. Glenwood); and MC Psalm One on Sunday (9 PM, Skybar, 2242 N. Lincoln). On Saturday at 9 PM, Women & Children First (5233 N. Clark) presents Sister Spit: The Next Generation, hosted by author and editor Michelle Tea and described by Decibelle as the “queerest indie literary road show in the land”; it features a variety of writers and performance artists, including “indie poet icon” Eileen Myles.
