Enough with the green beer. The classiest way we can think of to celebrate St. Patrick's Day is with Celtic Woman, the Irish quartet that has become a mainstay on PBS and at the Xcel Energy Center. On last year's "Emerald: Musical Gems," the singers revisited many old favorites, including "Danny Boy," "Dúlaman" and "Bridge Over Troubled Water." This year's 75-concert tour will feature two new singers, Mairead Carlin and Lynn Hilary. (7 p.m. Mon., Xcel Energy Center, $41-$71. ) Bream
POP/ROCK
Forget about sending singers concert requests via a Website or social media. Mike Doughty is going old school. Scribble your request — or question — on a slip of paper and toss it in a jar. The former Soul Coughing frontman will then allow his randomly drawn pieces of paper to dictate his set list. He's calling it his Question Jar Tour. Ask him about recording solo albums in Minneapolis with producer Dan Wilson or what salacious stories he left out his 2012 memoir "The Book of Drugs" or anything you want. (7 & 9 p.m. Fri.-Sat., Dakota, $25.) Jon Bream
Has Disasteratti turned into a funk band? Not exactly, but the scorching Minneapolis noise-rock trio's new album for Learning Curve Records, "Cerebral Hack Artists," boasts several songs with snaky grooves and more rhythmic fluctuations, vs. the metallic pounding and all-roar approach of past efforts. Frontman Dari Kaveh still howls and screams like the best of the Amphetamine/Reptile-era "singers," but he also shows off a slower-stewing, Kurt Cobain-like mellow dark-side here. Buildings, Mrs. and Animal Lover open the release party. (9 p.m. Fri., 7th Street Entry, $5.) Chris Riemenschneider
If the local radio hit about his mom playing soccer for the National Side wasn't enough of a clue, Romantica frontman Ben Kyle is a grade-A Americana singer but originally hails from Ireland. That's just one of many reasons his band is a great choice to take over St. Paddy's Day duties at First Ave. Back from an extended break after guitarist Luke Jacobs relocated to Texas, the local folk-rockers will be joined by a couple other whiskey-soaked twang-rock acts, White Iron Band and Silverback Colony, as well as the Minnesota Police Pipe Band. (8 p.m. Mon., First Avenue, $10-$15.) Riemenschneider
After bouncing around different venues for St. Patrick's Day in recent years, the Twin Cities' most Irish non-Celtic band the Belfast Cowboys landed at the Turf Club last year and seem to have found their pot of gold. Or at least they probably get a good drink tab there. Frontman Terry Walsh and his nine-piece band play the works of Van Morrison with fun and finesse, and they know some great originals and covers by other Irish rock legends, too — all of which will come in handy, with multiple sets to fill the night. (7 p.m. Mon., Turf Club, $5.) Riemenschneider
Things always seem to be going up and down for Demi Lovato. Let's see, the 21-year-old former Disney darling announced that she wouldn't return as a judge for the fourth season of "The X Factor," then a few weeks later it got canceled. Lovato released "Let It Go" as a single, only to get trumped by Idina Menzel's Oscar-winning version of the same song. Lovato's book, "Staying Strong: 365 Days a Year," was published last fall and nothing could stop it from topping the New York Times' bestseller list. Now she's on tour promoting her fourth album, "Demi," featuring the electropop hit "Heart Attack." Opening are two acts launched on "The X Factor": England's spicey girl group Little Mix and faceless U.S. vocal group Fifth Harmony. (7 p.m. Tue., Xcel Energy Center, $29.50-$65.) Bream
Together for over three decades, New Orleans bar favorites the Radiators were a jam band long before the term was in common parlance. Now guitarists Dave Malone and Camile Baudoin, and drummer Frank Bua Jr. are back in a new quintet with an amusing name, Raw Oyster Cult. Better do a load of tie-dyes, because their Twin Cities debut is a two-night affair also featuring John Gros, the beefy keyboardist and lead singer of another veteran Crescent City combo, Papa Grows Funk. (9:30 p.m. Fri.-Sat., Bunker's, $25.) Tom Surowicz
HIP-HOP
While seemingly every rapper under the sun eventually trades in their microphone to step in front of a camera, Donald Glover has gone in the opposite direction. The Los Angeles actor and comedian gave up his role on the NBC sitcom "Community" — he was a writer on "30 Rock" before that — to focus on his recording career as Childish Gambino, a Wu Tang-inspired stage name that belies the serious tone of his second album, "Because the Internet." The record put a personal, confessional spin on his otherwise playful, danceable songs such as the single "The Worst Guys." (7 p.m. Tue., Myth, $30, all ages.) Riemenschneider
