"Overground" is a song written and recorded by British rock band Siouxsie and the Banshees. It was co-produced with Mike Hedges and included on The Thorn EP. The song originally appeared on the Banshees' debut album The Scream in 1978. The Thorn version of "Overground" was later included in the 2004 box set Downside Up.
In its original version, "Overground" was presented as a post-punk song which matched the musical style of The Scream. Siouxsie and the Banshees re-recorded the track with elaborate, lush orchestral instrumentation with a flamenco acoustic guitar for its inclusion on the four-track The Thorn EP.
"Just how far they've come is shown by the '84 reworking of 'Overground'…" observed Dave Morrison in a review of Twice Upon a Time: The Singles, "where the teeth-grating abrasion of old gives way to a panoramic sound of martial drumming, strings and flamenco guitars."
"Overground" was released as a single with "Placebo Effect", another track appearing on The Thorn, as its B-side. It peaked at number 47 on the UK singles chart.
