If the Ghost Ball proves too crowded or too douchey for your tastes, Cap'n Mike and his kooky crew have a more unpretentious option for your All Hallows Eve. A big chunk of Winfield Scott Plaza will be fenced off for a two-day indoor/outdoor extravaganza of live bands, drunken distractions, and bizarre behavior. A costume contest will also be offered with prizes (including a Jägermeister dispenser) for the best-dressed guy and girl as well as the "most offensive outfit." The always-popular Chuey the Rock 'n' Roll Midget will also be in the house and will likely sporting a fairly bizarre costume (last year he dressed as John Wayne Gacy-esque clown). Beat that Axis-Radius. 8 p.m., $5. (4251 N. Winfield Scott Plaza, Scottsdale, 480-874-2264).
Rev Theory at Tempe Marketplace (Friday)
Here's a deal that's sweeter than any Snickers bar stolen from your kid's trick or treat bag: alt-metal act Rev Theory ("Light it Up," "Far From Over") is scheduled to perform on the outdoor mall's District Stage and the gig is absolutely free of charge. Beezlewood (the newest band from Opiate for the Masses Ron Underwood) and local boys Howitzer open the show. 8 p.m. (2000 E. Rio Salado Parkway, Tempe)
G.G. Elvis and the T.C.P. Band at Jugheads (Friday)
It's true that G.G. Elvis and the T.C.P. Band -- a group of NOFX and Lagwagon refugees that somehow mashes together G.G. Allin's music with The King's -- could be one of the strangest ensembles out there, but it also brings to life the obvious similarities between the two musical figures. Each, in his respective time, made sounds that folks didn't get for a while. Both hoarded interesting lifestyles in private. And, last but not least, each of their bottom halves did controversial things during performance (Elvis with that hip shake; Allin once took a steaming heap onstage). The Freeze, Bro-Loaf, Nunzilla, and Killing Eve will also perform. 8 p.m.; $5 with costume, $7 without. (5110 E. McDowell Rd., 602-275-1039). -- Steve Jansen

Plan 9 from Outer Space at Trunk Space (Saturday)
