Welcome back to AVC Sessions, our new series where we bring in an artist, band, musician, singer, rapper, etc. to perform three of their tracks. This week, Australian indie rock group Gang Of Youths visits The A.V. Club studio to play a few songs for us. In the final performance from its session, the band previews “Do Not Let Your Spirit Wane,” a new track from its upcoming album, Go Farther In Lightness.
