Mare Vitalis (Latin for "Sea of Life") is the second full-length album by Lawrence, Kansas-based emo group the Appleseed Cast. It was released on Deep Elm Records in 2000.
Exclaim! called "Storms" "a brooding, seven-and-half minute emo classic." Willamette Week called Mare Vitalis the band's "most essential album," writing that "[singer-guitarist Chris] Crisci and guitarist Aaron Pillar split the difference between their post-rock future and the driving punk that birthed the band." The Chicago Reader thought that "on 'And Nothing Less' and 'Santa Maria' the Appleseed Cast find nirvana through repetition." Vulture deemed it "oceanic indie rock." Stereogum named "Forever Longing the Golden Sunsets" in their list of "30 Emo Songs: Late 90s & Early 2000s Essentials."
