For the theory relating to large scale deformations of elastic structures, see Elastica Theory.
Elastica were a Britpop band who were popular in the 1990s, formed by Justine Frischmann after leaving Suede in 1991. Frischmann recruited the rest of the band members: Justin Welch (formerly of garage rock band Spitfire - drums), Annie Holland (bass) and Donna Matthews (guitar).
Their first single was 1993's "Stutter", which was a word-of-mouth hit largely due to the promotional efforts of Radio 1 DJ and Deceptive Records label-boss Steve Lamacq.
