On the Sunday of Life is the debut album of English progressive rock band Porcupine Tree. It compiles tracks that Steven Wilson produced and recorded for two cassette-only releases, Tarquin's Seaweed Farm (1989) and The Nostalgia Factory (1991). The rest of the music from these tapes was released three years after in the compilation album Yellow Hedgerow Dreamscape.

This is the place to start to lead you onto other ares of Steven's work and indeed other members of Porcupine Tree (Richard Barbieri - Japan) to name a few.

Most of the lyrics were written by Alan Duffy, a school friend with whom Steven Wilson had lost touch a few years before the album was released. The album title was chosen from a long list of nonsense titles compiled by Richard Allen of Delerium.
