Breaking up is hard to do, as Dirty Projectors’ mastermind David Longstreth and former Dirty Projectors’ singer Amber Coffman can attest.
Former San Diegan Coffman joined the New York band in 2006 as a singer and rhythm guitarist. She and singer and lead guitarist Longstreth were a couple until 2012, but worked together for several more years.
He produced her 2017 debut solo album, “City of No Reply,” but not before suddenly releasing a wildly ambitious solo album, titled “Dirty Projectors,” about their breakup.
On Saturday, Longstreth and the latest edition of Dirty Projectors kicks off its first tour in five years here at the Music Box. The band now teams him, bassist Nat Baldwin and drummer Mike Johnson with three new members — percussionist-singer Felicia Douglass, guitarist-singer Maia Friedman and keyboardist-singer Kristin Slipp.
It remains to be seen who covers Coffman’s lead vocal parts or how many songs the band will preview from its new album, “Lamp Lit Prose,” which is due out July 13 and features such guests as Haim and Fleet Foxes’ Robin Pecknold.
The one song released from the album so far, “Break Through,” features intricately snaking guitar lines that suggest Longstreth has been spending a fair amount of time listening to the music of Nigerian music great King Sunny Adé. It is also the first song in memory that name-checks both Italian film giant Federico Fellini and Strokes’ singer Julian Casablancas.
