In relation to the Mini Jazz Klub series (more to come on that subject later) I noticed these other Panton LPs with the famous bands Jazz Q, Energit and Impuls (plus another band called CHASA with a very disappointing ethnic entry, who apparently never had an LP release). I think you have already all the albums of those 3 biggies. (In relation to the middle band, the Lubos Andrst album Capricornus is one of my all-time favourite fusion albums too featuring as it does that supernatural European fusion mix of chamber music and intelligent composition.) And Martin Kratochvil with that amazing April Orchestra posted years ago here played in Jazz Q, just to remind you.
As far as I know none of these tracks appeared on the released LPs from the seventies which the bands put out. Some, perhaps all, did show up later on the recent CD reissues.
From the first album it's Impuls' Sly mastery of hard fusion that just knocks me flat-out:
Now turning our attention to the possibly superior second album the most noteworthy entry is the Jazz Q track oddly entitled Na Shledanou, Joan:
Martin really had a gift for combining (early "mashup"?) blues or jazz-based patterns with his classical education in music, as in this piece.
