Rockets were a French space rock band that formed in Paris in 1974.
 Some of the former members had played together since 1970 in a local band called Crystal.
 In their most successful era (1977–1982) the line-up comprised vocalist Christian Le Bartz, bassist and vocalist "Little" Gérard L'Her, guitarist and keyboardist Alain Maratrat, drummer and percussionist Alain Groetzinger, and keyboardist Fabrice Quagliotti.
 The band went through a number of name changes, being known as the Rocket Men and Rok-Etz, among others.
 In the year 2000 Fabrice Quagliotti decided to reform the band (initially with the name Rockets N.D.P.), but with a totally different line-up.
 This brought to an anomalous situation, as far as none of the former members agreed to hold a reunion.
 In fact, the last former member to leave the band was Alain Maratrat, in 1992.

 Their style of music is labeled such things as "math rock," "indie rock', "post rock" "experimental rock," and instrumental rock, among others.
 The song structures mainly focus around clean and melodic, yet heavily complicated and technical playing which contains pleasant hooks, backed by fittingly technically demanding drumming.
 The band broke up after releasing their debut EP, Lava Land, on the label Team AV, in 2005.

 They have sold 21.5 million RIAA-certified albums in the United States and their worldwide sales are estimated to be between 100 million and 150 million.
