After recording four ten minutes cassettes they released their sole album in 1981.

Both the album and the title track (the album's sole single) unfortunately failed to chart.

Yessongs is the sole album from this series not to have bonus tracks.

The concerts, like the group's sole album, consisted of completely improvised music.

The sole album was released over the internet, with links on the official Sigh website.

The band's sole album, Premiere, came out in 1979.

Amesoeurs is the sole album by the band of the same name.

Their sole 1970 album has been described as "an item for the psychedelic rock collector's wish list".

Alongside their sole album, several extended plays and singles were also released by the band.

Years later, the band is still popular in underground circles and their sole album remains a collector's item.
