American-born producer Matthew Dear has teamed up with indie duo Tegan and Sara for his new single, “Bad Ones.”

Dear has been fans of Tegan and Sara since first hearing their 2014 song "Walking With A Ghost," he says. And they went on to work together on a Tears For Fears cover in 2013.

After sending over a loop for "Bad Ones," Tegan and Sara wrote the verse and chorus "practically overnight," Dear said in a press release.

"I spent the next month working on it, turning a demo into a full-fledged song. Working with Tegan and Sara reminds me the best songs are born from an open and free process. Often times, we need to get out of our own way to let the magic happen, and this song is a bold reminder of that."
