Dec. 31 The Song Remains the Same w/ Ten Club and Surfer Rosa Horseshoe Casino, Council Bluffs 8 p.m., FREE, 712.329.6000 horseshoecouncilbluffs.com How often do Led Zeppelin, Pearl Jam and The Pixies get to share a stage? Probably as rarely as cover bands of those groups sharing one. (Well, except one band is long broken up with a dead drummer and another is on-again-off-again due to infighting.) But that's just the confusing New Year's Eve party in store at the Horseshoe Casino, where Pixies cover band Surfer Rosa will lead to Ten Club, hopefully Nebraska's only Pearl Jam cover band, which will lead to The Song Remains the Same, a Led Zeppelin tribute band hammering their way to Valhalla. It may be a mutt, genre wise, but the admission is free and it's New Year, and you can just think of it as free-form radio, except in tribute form. And hey, you're not the one who has to pay the ASCAP royalties!
