I totally get this: I was blown away by Jaco's chops when he broke through, and reverred his technical nous. 'Heavy Weather' is in my top 5 albums of all time however, for me, it was always Percy Jones. A total pioneer of explorative, expansive - sometimes left-field - fretless bass... and that right hand technique!!!
In fairness, unsolicited, Jaco came upon Percy by chance and heard him playing in the flesh... he had the utmost respect for Percy and his approach.
