8 p.m. Friday
The Center for the Arts
Where the term “jam band” gets cloudy is in the notion that the “jams” are indeed completely improvised on the spot, rather than lengthy pre-written instrumental rock compositions. With the Everyone Orchestra, it has never been truer. Conductor Matt Butler has been shepherding this rock wizardry project for years, with an ever-rotating cast of top-tier musicians ditching the script and letting their playful lunacy fly creatively. This tasty iteration of the orchestra includes Joel Cummins (keys) and Kris Meyers (drums) of Umphrey’s McGee; Ben Thomas (vocals) and Jamie Kime (guitar) of Zappa Plays Zappa; Kai Eckhart (bass) of Garaj Mahal/John McLaughlin; and “special guests.” 314 W. Main St., Grass Valley. $32. www.thecenterforthearts.org.
8 p.m. Wednesday
First, a clarification: Neither member of this Brooklyn/Cincinnati duo is named “Tanya.” The bio tells us the name was chosen to “trick hip-hop crate-diggers and sample-searchers into thinking the record was an old-school soul singer.” Sneaky! Almost as sneaky as their seasoned and chiseled approach to hip-hop, which is reminiscent of De La Soul. They’re touring after a week at SXSW in Austin, Texas. They perform here with Berkeley-based spitfire electro-soul vocalist Corina Corina (we believe her name actually is Corina), with local standouts Task1ne and Dre-T opening. 1400 Alhambra Blvd, Sacramento. $9. www.bluelampsacramento.com.
The Lower 48
8 p.m. Thursday
Regulars of this Curtis Park hooch parlor know that Thursdays are reserved for the vinyl-spinning series known as “Trash Rock,” which celebrates its one-year anniversary with help from Portland, Ore.’s the Lower 48. At first glance, this uppity trio doesn’t quite look the part for a bar with a jukebox that smacks you around with Cash and Cline, but a deeper dive tells you they’re totally Hideaway rock ’n’ roll ilk. They’re like a band of would-be British Invasion pop rockers who instead of “invading” said to themselves: “Screw it; let’s just stay here and jam.” 2565 Franklin Blvd, Sacramento. $5. www.thelower48.com
Looking ahead: Dead Milkmen, April 21 at Harlow’s
Ambivalent and dark underground punk is always going to have its place in the world, which explains why the Dead Milkmen have been at it for the better part of 30 years. 2708 J St., Sacramento. $25. www.harlows.com.
