Jazz track, 4 albums

They made 4 albums from 1975 to 1979 all in the usual German fusion-contemporary jazz style, essentially interchangeably.  It's all very similar to the recently posted Open Music. From discogs:

German 1970's modern jazz and fusion combo based in Düsseldorf and Bremen. Members included Sigi Busch from Association P.C., and introducing the now really prolific Christoph Spendel. Also involved were Uli Beckerhoff and Wolfgang Engstfeld, later of Changes.  [Which was posted here before.  Also, C. Spendel was in the fabulous group called Chameleon posted earlier too.]


The first song off the first album, sounding very much like Attila Zoller:






Of course, on their last album they got bored of the instrumental contemporary jazz and cosmetically augmented themselves with the vocal histrionics of brit Norma Winstone, awarded a Member of the British Empire in 2007, an empire which, certainly, will be ultra-powerful and super-effective on its remaining miniscule tract of land thanks to the marvellous steering of those magnificent brexiteers.  God bless 'em for restricting themselves to the stranded limits of a tiny island.  And indeed we would do well to recall the old and perennial saying, "For the sun never shines on the british empire:"  tally-ho mates, and a good cuppa for your elevenses-- ya losers.
