• Lotus with Circles Around The Sun and Ghost-Note are set to perform today at 5:30 p.m. at Heuser Park in King of Prussia. Lotus has influences of classic electronic dance music, funk, post-rock and dance-rock. Over the years, their unique musical blend of electronica with jam music has helped forge a new path in the jam band landscape, influencing many younger bands. Circles Around The Sun’s fourth studio album traverses toward galaxies unknown. Synth-drenched excursions into outer-spatial sound design, the six-song release welcomes guitarist John Lee Shannon to the fold, a longtime peer and tour mate who joins bassist Dan Horne, keyboardist Adam MacDougall and drummer Mark Levy. Ghost-Note is a percussion-based funk, hip-hop and jazz fusion group from Dallas, with a rotating membership based around founding drummer Robert “Sput” Searight and founding percussionist Nate Werth, two members of the jazz band Snarky Puppy. Tickets start $61. For more information, go to tixr.com/groups/rsp/events/.
• Indigo Girls with Dar Williams are the headliners at the River Roads Music Festival Saturday at Heuser Park in King of Prussia. Seven acts are on the bill, and performances begin at 1:30 p.m. Indigo Girls have reunited with their strongest backing band to date to create “Look Long,” a stirring and eclectic collection of songs that finds the duo of Amy Ray and Emily Saliers chronicling their personal upbringings with more specificity and focus than they have on any previous song-cycle. These 11 songs have a tender, revealing motion to them, as if they’re feeding into a Super 8 film projector, illuminating a darkened living room: Saliers and Ray are tackling the mechanisms of perspective. In this moment of delirious upheaval, “Look Long” considers the tremendous potential of ordinary life and suggests the possibility that an honest survey of one’s past and present, unburdened by judgment, can give shape to something new — the promise of a way forward. Williams’ lyrics contain bouquets of optimism, delivered on melodies alternating between beguiling lightness and understated gravity. Williams strongly believes that all of us possess our own power and ability to achieve, and she rejects the exceptionalism that encourages us to “admire that yonder star,” while making us feel small and insignificant; unworthy of shining on our own but hoping to catch enough distant light to inspire some tiny accomplishment. Tickets start at $77. For more information, see tixr.com/groups/rsp/events/.

• The tribute band Live At The Fillmore is set to perform Saturday at 8 p.m. at the Sellersville Theater in Sellersville. The original Allman Brothers Band performed regularly at New York’s Fillmore East Auditorium run by legendary promoter Bill Graham and often referred to as the “church of rock and roll.” The Allman Brothers Band played often enough at Fillmore East to be called “Bill Graham’s house band.” It was here and at other New York metropolitan-area venues like Passaic, N.J.’s, Central and Capital theaters and Central Park’s Schaefer Summer Concert Series where Lou Maresca and other members of Live at the Fillmore first heard the Allman Brothers Band perform beginning in 1970.
