WILLIE NELSON/ALISON KRAUSS/KACEY MUSGRAVES
Generations of country music — some royalty, others rising — will come together in this star-studded roots music celebration. At 81, Nelson has polished his performances according to a well-worn set list of classics (“On the Road Again,” “Whiskey River”), but hopefully he’ll pepper it with songs from his fine new album, “Band of Brothers.” Krauss, the beloved Grammy-winning nightingale of bluegrass, will arrive with her backing band, Union Station (featuring Jerry Douglas). And Musgraves, a young artist who blurs the line between country and pop, will get the party started.
June 17, 7 p.m. Tickets: $30-$80. Blue Hills Bank Pavilion. 800-745-3000, www.livenation.com
Her first proper release, “The Double EP: A Sea of Split Peas,” was oddly overlooked last year, a reminder that obvious talents aren’t always noticed at first. Barnett (above), an Australian singer-songwriter who imbues her story songs with a wry sense of humor that sometimes recalls that of Jonathan Richman, has a way of spinning the mundane into something marvelous. With folk-blues wild man Benjamin Booker opening. June 18, 9 p.m. Tickets: $15, $13 in advance. The Sinclair, Cambridge. 800-745-3000,
RUFUS WAINWRIGHT In between studio albums, Wainwright is nonetheless busy with his latest labor of love: getting his first opera, “Prima Donna,” professionally recorded with the help of a PledgeMusic fan-funding campaign. He hit his goal earlier this month. With three new songs released on “Vibrate,” his recent best-of collection, Wainwright will no doubt have free reign to survey the range of his discography, from his troubadour origins to his flights of fancy in chamber pop, art songs, and his love of Judy Garland. June 18, 7:30 p.m. Tickets: $44. Somerville Theatre. 800-745-3000, www.ticketmaster.com
