In October 2017, Grizzly Bear performed "Mourning Sound" live on KCRW, marking a significant moment shortly after the release of their fifth studio album, *Painted Ruins*. This album, which came out on August 18, 2017, was notable for its intricate soundscapes and the time-consuming process of creation, taking five years to complete. The performance showcased the band’s evolution and their return after a hiatus, featuring lush harmonies and complex arrangements that are emblematic of their style. Additionally, *Painted Ruins* was highly anticipated, reflecting both the band's growth and the changing dynamics of the music industry. This live session at Apogee Studio not only illustrated the band's technical prowess but also highlighted their ability to connect deeply with audiences through intimate performances.
