The Madeline Mixtape is Summit Sound Collective's debut compilation album, featuring 14 arrangements of songs from the Celeste soundtrack.

This album is a fundraiser for Trans Lifeline, a grassroots hotline and microgrants 501(c)(3) non-profit organization offering direct emotional and financial support to trans people in crisis – for the trans community, by the trans community. 100% of sales go directly to Trans Lifeline, minus the cut that Bandcamp takes.
