Porcupine Tree recorded their Coma Divine live album at the Frontiera Club, Rome in March 1997 over the course of three nights. The album was largely taken from the third night, meaning they've been sitting on two additional night's worth of material for years.
Porcupine Tree has now uploaded the second night of recording to Bandcamp under the title Coma:Coda. The album features "Signify, Dislocated Day (incomplete but fun because of an impromptu drum solo!), and Radioactive Toy," as well as a composition titled "Cryogenics" that was written specifically for the live album and ended up not making it.
