Flammende Herzen

Rother plays guitar, electric piano, bass, synthesizer, organ and electric percussion, Jaki Liebezeit plays drums, and Conny Plank co-produced and engineered. It is entirely instrumental, all by Rother. Rother told Tone Glow in 2024 that he recorded guitar ideas at home in Forst on a 4-track before working with Liebezeit, and told Side One Track One that he has a very clear memory of showing Liebezeit a very rough sketch with just his guitar. He knew Liebezeit from 1971 concerts with Kraftwerk. Its German success was, in his words, utterly amazing and surprising; Derek's Music Blog calls it not a commercial success and overshadowed by punk, while Groenland calls it a breakthrough. A German film about misfits in New York used the music and took its title, Wikipedia names it Flaming Hearts (1978).

AllMusic's Thom Jurek gave 4.5 stars, and freq.org.uk says it extends what Rother began on the first side of Neu! 75. Reissues include Polydor in 1982, Polygram CD in 1990 and Random Records with bonus tracks in 1993, which add the film remix and a chill remix.
