COUNTRY The second and majorly upgraded Country Splash continues tonight with the uncrowned king of country, Kenny Chesney, who has sold more concert tickets this decade than anyone in the genre; spitfire Miranda Lambert, who will burn it up with "Kerosene" and "Gunpowder and Lead," and fast-rising trio Lady Antebellum. On Saturday, Darius Rucker, the Hootie frontman turned Nashville star who is an invigorating performer no matter what the genre, will set the table for Rascal Flatts, the harmony-obsessed country-pop trio. (1:30 p.m. today-Sat., Float-Rite Amphitheater, Somerset, Wis., www.countrysplash.com) (J.B.)
POP/ROCK The Offspring never turned into a top-tier band like Green Day, though both pushed punk-rock into the mainstream with snarky hits in the mid-'90s. But the fly white guys from Huntington Beach, Calif., have hung onto their young skateboarder audience and are even earning a lot of radio play again with their latest album, "Rise and Fall, Rage and Grace," featuring the fist-pumping singles "You're Gonna Go Far, Kid" and "Hammerhead." It's no four-star rock opera, but it does show that these guys can get serious and still seriously rock. Boston's Irish-punk faves the Dropkick Murphys and Southern Cali newcomers Time Again open. (6:30 p.m. today, Roy Wilkins Auditorium. $39.50-$42.50.) (C.R.)
Part of the Nashville contingent that rebels against the wussies on Music Row by being extra wild and manly, Th' Legendary Shack Shakers kick up punkabilly and have an excellent showman/frontman in JD Wilkes. The quartet just finished a new album, "AgriDustrial," due in the fall. (9 p.m. today, 400 Bar. $12-$15.) (C.R.)
Powerhouse singer Lydia Pense, a mainstay for four decades on the San Francisco scene (and featured in this month's DVD "Fillmore: The Last Days"), brings her latest incarnation of brassy blues-rockers Cold Blood to town. She actually recorded "Piece of My Heart" before Janis Joplin transformed it into a classic. (8:30 p.m. Sat., Minnesota Music Cafe, $15-$20.) (J.B.)
This weekend's 36th annual Back to the '50s street-rod celebration features countless cool cars and two of the Twin Cities' biggest (and refurbished) garage-rock bands of the '60s -- the Castaways (1965's "Liar Liar") and the Trashmen (1963's "Surfin' Bird"). (6:30 p.m. Sat., State Fairgrounds, $10.) (J.B.)
You can't beat the setting (the Mississippi riverfront) or the price (free) of the Stone Arch Festival for the Arts, which also offers one of this summer's more colorful music lineups -- particularly of female artists, who are shamefully lacking at Taste of Minnesota and other events. Especially recommended Saturday are masterful pluckers Spaghetti Western String Co., Britrock quintet the Idle Hands, neo-folk team Roma di Luna, twangy kids Caroline Smith & the Good Night Sleeps and songwriters Eliza Blue, Dan Israel and Brad Senne. Sunday's highlights include a trio of rustic indie-rock bands, the Absent Arch, Me & My Arrow and the Wars of 1812, plus Americana rocker Jason Shannon, soul-rock balladeer Chastity Brown and Parisian cabaret-styled Cafe Accordion Orchestra. (11 a.m.-6 p.m. Sat.-Sun., St. Anthony Main and Father Hennepin Park, Mpls. Free. Set times at www.StoneArchFestival.com.) (C.R.)
Ah, the Church. "Under the Milky Way" was the stargazing anthem for music fans who grew up on "120 Minutes," and the Australian quintet produced quite a few albums' worth of similarly swooning and ethereal gems. The group's core trio -- Steve Kilbey, Marty Willson-Piper and Peter Koppes --have taken time out for solo albums but never stopped making albums together. Their latest, "Untitled #23" (yep, their 23rd!), is squarely ho-hum, but the songs will fit in OK around old favorites. They're on tour with another old alt-rock vet, Adam Franklin, who fronted the mighty guitar-swirly British band Swervedriver. (8 p.m. Sun., Varsity Theater. $23-$26.) (C.R.)
A pedal-steel guitar player featured on seemingly every other CD that comes out of the Twin Cities, Joe Savage is getting some deserved payback after being diagnosed with prostate cancer (caught early, thankfully). Trailer Trash, Hookers & Blow, Romantica, the Dollys, Pat Donohue, Pop Wagner and many others have signed on for a fundraiser to help offset his medical expenses. Even ol' Garrison Keillor will be on hand for a reading. (3 p.m.-midnight Sun., Minneapolis Eagles Club. $10 or more.) (C.R.)
