The soundtrack to the comic strip "Lou! Sonata 2" will plunge you into the heart of Dead Dung Fest, the music festival organised by the heroine and her friends. The ten (fictional, created by the Krystal Zealot collective) bands who perform there are present on this record.

Existential bossa nova (Le Marquis du Néant), Swedish electronic folk (Frikoppling), steamy fusion (Cyriak's Oak) or relaxed disco pop (Fur Pants): each track reinterprets the themes of the story and the moods of the characters.

The vinyl edition includes several bonus tracks based on the world of "Lou! Sonata" and the Dead Dung Fest: a poster, a series of 10 illustrated album covers corresponding to the different groups, the flyer and the official festival woven bracelet.
