Bleachers

Bleachers is essentially Jack Antonoff's solo project, which he started planning in 2012 when he was on tour with his band Fun, known for the hits "We Are Young" and "Some Nights." In Fun, he played a variety of instruments and contributed to the songwriting, but in Bleachers he runs the show, with complete creative control. He's also the lead singer, so he's much more visible in Bleachers than in Fun, where Nate Ruess was the frontman.

Before launching Bleachers, Antonoff did songwriting and production work for Tegan and Sara ("How Come You Don't Want Me"), Sara Bareilles ("Brave") and, most notably, Taylor Swift ("Sweeter Than Fiction"). He's since become one of Swift's go-to collaborators and has worked with many of the most popular acts in music, including Sabrina Carpenter, Kendrick Lamar and The 1975. He's known for having a wellspring of ideas and being very easy to work with.

The first Bleachers single, "I Wanna Get Better" in 2014, reflects Antonoff's state of mind at the time. He wanted to get better from lingering health issues, including a bout of pneumonia in 2011 and an ongoing depression. It's a very upbeat song musically, though, so many listeners didn't pick up on that.
