At its best, music has the power to transport the listener to another point on the space-time continuum. For Orquesta Akokán, that time and place is something like the Tropicana in Havana, sometime before the Cuban Revolution. Picking up the timbales from fellow Cuban traditionalists Buena Vista Social Club, vocalist José “Pepito” Gómez and the Orquesta are masters of big-band jazz and mambo. For their self-titled album on Daptone Records — the ringleaders of the funk-soul revival and home to dearly departed singers Sharon Jones and Charles Bradley — the group lays down rhythms that demand dancing, no matter where you are. Saturday at 3:45 p.m. at Rosslyn Jazz Fest . Festival runs from 1 to 7 p.m. Free.
It’s almost to the point of parody, but it’s a good time to be “Lil” in hip-hop, with Lil Uzi Vert, Lil Yachty and Lil Pump ushering in rap’s new wave (with the king of the Lils, Wayne, set to reclaim his throne if “Tha Carter V” ever drops). One similarly monikered rapper is 23-year-old Atlanta native Lil Baby. Baby raps with the straightforward, no-nonsense approach of his name, name-dropping designer labels and gun slang while counting impossibly high stacks of cash. But if this Baby’s Auto-Tuned, singsong style has a father, it’s not any of his fellow Lils — it’s Young Thug. Saturday at 8 p.m. at the Fillmore. Sold out.
For nearly a decade, Ava Luna has mined R&B, funk, post-punk, Krautrock and more as inspiration for angular riffs, off-kilter rhythms, and — most notably — the vocals of Carlos Hernandez, Becca Kauffman and Felicia Douglass. But after so long as a band, the Brooklyn five-piece mixed things up while recording forthcoming fourth album “Moon 2.” Hernandez stepped back as the bandleader, and the band members tried new instruments and roles. The results include synth-laced new wave on “Centerline” and the deceptive dance-punk of “Deli Run,” which turns a pun into a koan: “If I go for a deli run, will you roll with me?” Sunday at 9 p.m. at Comet Ping Pong. $13.
When British duo Let’s Eat Grandma sings, “I’m only seventeen/ I don’t know what you mean,” they must mean in relationships, or in life — but certainly not in the studio. The teenage team of childhood friends Rosa Walton and Jenny Hollingworth are preternaturally self-assured in their songcraft, making avant pop that sounds like lullabies from the Upside Down. On this year’s “I’m All Ears,” the pair’s spaced-out, secret-garden creations became even more baroque, due in part to production by pop provocateur Sophie, but mostly thanks to their ability to turn the ambiguities of teen life and love into stream-of-consciousness poetry, both lyrically and sonically. Thursday at 7 p.m. at U Street Music Hall. $15.
