Storm Force Ten is the tenth studio album by British folk rock band Steeleye Span, released in 1977 by Chrysalis Records.

Arguably "The Victory" is the best [citation needed] of their long tracks because of the masterful variations in tempo, instrumentation and choice of voices.

[citation needed] According to Hugh Fielder in the pop paper Sounds in 1977, there is an uncredited musician here - Mike Batt playing synthesizer.

[citation needed] Instead John Kirkpatrick plays accordion, giving the whole album a very distinct sound from the rest of the band's output.

Q (May 2007, p. 135): "It was Steeleye Span who carried the British folk rock banner into the '70s, with Martin Carthy's guitar (plus honking accordions and the clear, high voice of Maddy Prior, the band's one constant through endless line-up changes) ringing out on this overlooked album.
