It’s time for another edition of The Watkins Family Hour, the unpredictable gathering that mixes bluegrass heartache, folk-rock longing and classic-rock covers by unexpected musical collaborators paired with comedic guest stars. Although the monthly soiree at Largo often features such stellar visitors as Fiona Apple and Benmont Tench (Tom Petty & the Heartbreakers), the show is carried by Sara and Sean Watkins of Nickel Creek. The sibling hosts have their own deep catalogs of songs — both solo and together — and their melodious voices are twined with Sean’s artfully adept acoustic-guitar embellishments and Sara’s expressive fiddling. No two editions of The Watkins Family Hour are ever the same, and it’s difficult to guess about which celebrity pals might drop by this month, but the Watkins’ songs alone are enough to make this a compelling draw. With Langhorne Slim, Mike Viola and others.
Largo at the Coronet, 366 N. La Cienega Blvd., L.A.; Wed., June 26, 7:30 p.m.; $30. (310) 855-0350, www.largo-la.com.
