A good night in Philadelphia for live music: 1990s indie girl Liz Phair (pictured) – now decidedly a woman at 43 – plays the TLA and will likely be rapping, as she does on “Bollywood” (hear it here)  from her new album, Funstyle; the two guys that make up super duper Austin electro-funk duo Ghostland Observatory bring their laser show and bowel-rupturing bass synth sounds to the Troc; speaking of Texas, but drastically more unplugged, is Alejandro Escovedo at World Cafe Live; and Usher, who has released not one but two albums this year, does his thing at the Wells Fargo Center… And for something completely different, Cabaret Red Light does a bawdy burlesque version of The Nutcracker at the Painted Bride. Enjoy!
