Immediate Family

The session musicians who helped create the soundtrack of 1970s pop step into the spotlight in the director Denny Tedesco’s documentary.“Immediate Family,” Denny Tedesco’s amiable documentary, could use a subtitle, as it’s not an intimate domestic portrait. It focuses on the currently touring rock band that comprises session players who defined the sound of American pop and rock in the 1970s, while for decades playing with the likes of James Taylor, Linda Ronstadt, Carole King, Stevie Nicks, Jackson Browne, Warren Zevon and more.Tedesco is the son of the West Coast guitar great Tommy Tedesco, and he clearly has a knack for getting musicians to open up. The band members — the guitarists Danny Kortchmar, Waddy Wachtel, Steve Postell; the bassist Leland Sklar; and the drummer Russ Kunkel — all relate their individual bios in relaxed, candid fashion. “Immediate Family” takes its time limning their skills and showing how they survived the 1980s, when session gigs became scarce. (Kortchmar’s remedy was to embrace new music technology and use it to boost Don Henley’s solo career after the Eagles disbanded.)Kortchmar’s playing is always in the service of the song and whatever depths that song is trying to plumb. Kunkel’s drumming is metronomically perfect, with powerful fills. Sklar’s sinuous bass playing reminds one of the influential jazz legend Steve Swallow, with a more pop sensibility. And Wachtel is a rhythm master with a bottomless bag of licks and leads. The chord structure of Zevon’s “Werewolves of London” is elemental, but Wachtel’s practically nonstop nasty embellishments make lines like “He’ll rip your lungs out, Jim” really sing. Postell, a decade younger than Sklar, the most-senior bandmate, has a varied background that includes time with David Crosby, who appears here singing the praises of all of these musicians.Their stories are often funny, like one in which Wachtel recounts hammering out “Werewolves” all night with guest rhythm players Mick Fleetwood and John McVie, only to conclude that they had nailed the song on Take 2.Immediate FamilyNot rated.
