Opening acts. Music fans tolerate them (might discover a cool new band), venues love them (more time to sell booze and merch), and stars appreciate them (more time to primp and prep).
Why did Brandi Carlile have two support acts this year? Why was Nile Rodgers setting the table for Duran Duran? Why did Broadway star Ben Platt reach out to Aly & AJ to warm up his audiences?
In short, relationships.
That's how opening acts for concerts typically happen.
Platt's relationship with Aly & AJ goes back to when he was 9 or 10 and to a children's theater production in Los Angeles in which Aly Michalka played his older sister.
"We lost touch," said Platt, who tapped the Disney-launched sister act to open for him two weeks ago at Target Center. "They were sort of an iconic presence in my upbringing. When this opportunity came back around, I assumed they'd be too cool for me, but they were so into it."
Sometimes it is personal connections. Sometimes it's a manager, agent or record-label tie-in. Sometimes the headlining act chooses.
Guitarist/producer Rodgers worked on several Duran Duran recordings, dating back to 1984. He's considered the unofficial fifth member of the veteran British band, but he has his own longtime U.S. group, Chic, so they were a natural opener, as Duran Duran frontman Simon Le Bon explained.
