4 p.m. and 8 p.m. Wednesday at Sleep Train Arena
Just exactly how big has this musical act gotten over the last 15-plus years? There are actually two different iterations of the Trans-Siberian Orchestra simultaneously touring the country each holiday season, often doing two head-banging, laser-light-infused shows per day to keep up with demand. Dozens of commercials have employed TSO’s guitar-shredding, prog-rock reinventions of holiday classics and original yuletide compositions, and fans never seem to tire of syncing their outdoor Christmas lights to its blazing, baroque tunes (and uploading the videos on YouTube, of course). At this point, there’s no arguing Trans-Siberian Orchestra’s place as a holiday mainstay. The 2013 tour is being billed as the final performances of the group’s seminal 2004 face-melting album “The Lost Christmas Eve,” although the true crux of the orchestra’s catalog will always be the wildly inventive ELO-meets-Dickens masterpiece “Christmas Eve and Other Stories.” 1 Sports Parkway, Sacramento. $31-$61. www.sleeptrainarena.com
Never miss a local story.
8 p.m. Saturday at The Center for the Arts, Grass Valley
You could take your best shot at convincing the members of Moonalice that the late ’60s are over – but they’d probably just smile and reply with a seven-minute, psychedelic guitar solo. Forged in the ashes of the now-defunct Flying Other Brothers in 2007, this San Francisco ensemble has lassoed the spirit of Grateful Dead in its heyday, tapping into a nostalgia for the golden age of Northern California rock ’n’ roll. The list of music titans that the members of this collective have played with throughout their careers is arm-long and includes Phil Lesh, Jerry Garcia, John Fogerty, Bruce Hornsby, Rod Stewart and John Lee Hooker. The show is listed as a “dance concert” with limited seating – would they have it any other way? 314 W. Main St., Grass Valley. $15. www.centerforthearts.org
Reggie Graham Trio
6:30 p.m. Sunday at Harlow’s
According to a recent post on Harlow’s Facebook page, the venue gets “a lot of calls asking about jazz shows.” This shouldn’t come as a surprise, given the snappy decor and lounge-themed setup of the venerable midtown haunt. It’s a room absolutely begging for some jazz, although the club’s packed calendar doesn’t seem to feature the genre with any notable frequency. However, Harlow’s is answering the call(s) this weekend with Reggie Graham, a soulful, gospel-influenced local pianist and music educator whose resume boasts stints as an adjunct professor in jazz/rock at Sac State, musical director for a variety of different church groups and live performer with such jazz heavyweights as Dizzy Gillespie and Charlie Hunter. The trio also features Capital Jazz Project guitarist and University of the Pacific jazz professor Henry Robinett. 2708 J St., Sacramento. $10. www.harlows.com
Looking ahead: Two Gallants — Dec. 14 at Harlow’s
This indie-folk-rock duo released its glistening “The Bloom and the Blight” in 2012 after a three-year hiatus, sparking a roaring comeback for the beloved San Francisco-based act named after a James Joyce story. 2708 J St., Sacramento. $15.
