Con la pubblicazione in questi giorni di alcune ritrovate registrazioni con Elton Dean (epoca 1974) giunge pressoché a compimento lo straordinario sforzo di documentazione delle attività dei più celebri canterburisti d'Olanda, Supersister, dopo i due corposissimi volumi biografici e fotografici usciti in tempi recenti, Looking Back, Naked e Retsisrepus. Si tratta di brani dal vivo tratti da quello che allora fu l'ultimo tour del gruppo, successivo di poco al loro album Iskander, con approccio aperto all'improvvisazione sicuramente influenzato dalla presenza del Nostro. In formazione c'erano Robert Jan Stips, Ron van Eck, Herman van Boeyen e appunto Elton Dean: The Elton Dean Sessions.
Exactly 50 years ago, Supersister toured the Netherlands and Europe in its last and special line-up. The American saxophone player Charlie Mariano had just recently left the band and surprisingly ex-Soft Machine member Elton Dean was found as his successor. This also completed the circle that started out in the early 1970s with the ‘common sounds’ Supersister had with the British Canterbury scene, Soft Machine being an influential member. With primal band members Ron van Eck (bass) and Robert Jan Stips (keys & vocals), drummer Herman van Boeyen and Elton Dean, Supersister once again stood fore exciting and moving live concerts, in which not only well-known hits and their latest album Iskander were played, on top of that it was the virtuoso connecting improvisations that took the audience on a unique compelling adventure.
