The bands toured together across Europe earlier this year.
Against The Current have talked about the experience of touring with Fall Out Boy earlier this year on their MANIA European tour.
The band are guests on this week's Rock Sound Podcast and Chrissy Costanza revealed how she was inspired by seeing FOB's arena show every night on the road:
"In terms of what we've taken away from Fall Out Boy, as a band it was really cool for us because they've kind of done the same thing we've done where they were originally more pop-punky and now they're into this more pop world. So, for us it was really great to watch how they married the two in their live set because that's something that we're now faced with."
ATC have just released their new album 'Past Lives' and completed a European tour.
Check out the full podcast featuring an interview with Chrissy, Dan and Will and a track by track of 'Past Lives' on Spotify, Soundcloud, iTunes or wherever you get your podcasts.
