POP/ROCK
Aside from frontman Joe Newman's weird, unintelligible, high-nasal voice — he'd make a good Igor in a Frankenstein movie — Alt-J are about as scary as an episode of "Care Bears." It's just by chance the arty, wiry rockers from Leeds, England, are landing in town on Halloween night in support of their second album, "This Is All Yours." Perhaps the occasion will loosen up the stiff, inanimate vibe of their previous local shows behind the Mercury Prize-winning, 89.3 the Current-adored 2013 debut "An Awesome Wave." The new record is more downbeat and less jagged-edged, but half of it could make for a solid concert paired up with the best half of its predecessor. Brooklyn-via-London electro-pop duo Lovelife opens. (8 p.m. Fri., Myth, sold out.) Chris Riemenschneider
An influential early '90s shoegaze band that helped fill in where My Bloody Valentine left off, Slowdive is back after a 19-year hiatus. The British quintet — led by hush-toned co-vocalists Neil Halstead and Rachel Goswell — spent the summer playing European festivals. For their U.S. club tour, they invited one of their favorite quiet bands of old to open, Duluth's Low, who thankfully never went on hiatus. (9 p.m. Fri., Fine Line, sold out.) Riemenschneider
Tribute shows are often the Halloween party of choice for local musicians and music lovers, and this year offers a few promising ones. Hi-Fi Hair & Records is hosting a 1973-themed bash with Alice Cooper deep-cutters Sick Things — who specify they're a tribute to the Alice Cooper band, not just the man — along with Blue Öyster Cult revivalists Agents of Fortune. (9 p.m. Fri., 1637 Hennepin Av. S., Mpls., $7.) Lee's regulars E.L.nO. certainly won't bring you down, especially not with Joey Ryan & the Inks in tow to deliver a Bob Dylan set — which surely has to mean a Traveling Wilburys crossover, too. (9 p.m., Lee's Liquor Lounge, $10.) Riemenschneider
Twin Cities quartet Zebulon Pike — co-helmed by Happy Apple jazz bassist extraordinaire Erik Fratzke — has been cranking out thundering, neck-endangering prog-metal almost as long as their peers in Mastodon, whose Brent Hinds recently gave them a shout-out on his podcast. The all-instrumental band has been more on the down-low in recent years but is kicking back into gear with a fifth album to promote. Fresh from helping darken Surly Brewing's Darkness Day last weekend, Vulgaari opens with Chicago's Electric Hawk. (10 p.m. Sat., Triple Rock, $8-$10.) Riemenschneider
Macklemore & Ryan Lewis' same-sex marriage hit "Same Love" introduced the world to Mary Lambert, who sang the hook "my love, she keeps me warm." Her brand-new debut album, "Heart on My Sleeve," gives us a fuller picture of a powerhouse vocalist who is, by turns, earnest and humorous. There are shades of Tori Amos, Sara Bareilles, Carole King and even Joni Mitchell on these soul-baring, mostly piano-based originals. Seemingly preoccupied with life-affirming anthems, the 25-year-old discusses body image, sexuality and other personal topics. She also transforms Rick Springfield's pop/rock chestnut "Jessie's Girl" into a lesbian love ballad. Jillette Johnson opens. (9 p.m. Sat., Fine Line , $20-$35.) Jon Bream
A Har Mar Superstar set at First Ave is always a good time, especially since the Owatonna-bred showman put together his current backing band and put out last year's joyous retro-soul album "Bye Bye 17." This one should be especially good for smiles, though, as he has invited the Pizza Underground, a Velvet Underground tribute band led by his actor pal Macaulay Culkin. The cheek-squeezing child star of "Home Alone" fame has never been cheekier, as the band puts a pizza-themed twist on the VU classics, i.e. "All Pizza Parties" for "All Tomorrow's Parties." Could be fun once, anyway. Toby Goodshank and Ripper open. (9 p.m. Sat., First Avenue, $15.) Riemenschneider
Celebrating his 50th year in the music business and a new double-disc retrospective, "Still on the Levee," blues and folk songwriter Chris Smither returns to play his "hits" ("Love You Like a Man," "I Feel the Same," "No Love Today") and wonderful catalog of misses. In between songs, you get hip, self-deprecating, sometimes rambling stories. It's a big year for the New Orleans-raised troubadour, since he was also feted with the tribute album "Link of Chain," featuring renditions of his durable material by friends and aficionados including Dave Alvin, Loudon Wainwright III, Bonnie Raitt and Jorma Kaukonen. (8 p.m. Sat., Cedar Cultural Center, $20-$25.) Tom Surowicz
Motherhood slowed Alice Peacock, keeping her off the road for nearly two years. Having twins will do that. But the Nashville-based, White Bear Lake-born singer, guitarist and songwriter is now touring a bit, with a new concert album, "Live From Space." You may have heard Peacock's songs without realizing it, since they've turned up often on TV shows ("Smallville," "Dawson's Creek") and films ("Because of Winn-Dixie," "Win a Date With Tad Hamilton!"), and even a Hershey's ad campaign. (7 p.m. Sun., Dakota Jazz Club, $25.) Surowicz
