Dec. 31 Learning to Floyd w/ Disposable Heroes Stir Live and Loud, Harrah’s Casino 9 p.m., FREE, 21+, harrahscouncilbluffs.com I love Pink Floyd, from the sweeping guitars to the trippy synths echoing under Roger Water’s operatic vocals, so I’m glad there is a free cover show featuring their material. But really, “Learning to Floyd” was the best name they could come up with? Bad monikers aside, these guys are in their second year of performing Floyd covers that keep up with the originals note for note. They’ve even been known to run down the nine tracks that make up Dark Side of the Moon , my favorite nine-track album. Joining them for this New Year’s Eve gig are Disposable Heroes, who slay through Metallica songs like it’s nobody’s business.
