Orchid is Opeth's debut album. Even so, it shows signs of Opeth's signature sound that can be found in all of their releases: the combination of heavy death metal elements, as well as softer progressive elements such as acoustic guitars and clean vocals. Most of the songs on this album run for at least 10 minutes, with the exception of "Requiem", a short acoustic instrumental track, and "Silhouette", a three-minute piano interlude that is played by Anders Nordin.
Considered by many to be one of the pioneers of the "screamo" sound, Orchid combined a post-modern aesthetic with hardcore punk, releasing several now-hard-to-find EPs and splits as well as three full-length records. Orchid's influences are assumed to be Canadian hardcore band Union of Uranus and One Eyed God Prophecy, but band members more often cite the German bands Systral and Carol.
