Larry and Steve also put some of their duets on "Two for the Road" (Arista, 1977). I've been enjoying that one as well as "Twin House" with Catherine for around 40 years. There was also "Tributaries" with Larry, John Scofield and Joe Beck going trio in '79. I will have to find that Steve Khan solo effort on Arista.
As you know guys know, Side 1 of "European Impressions" was recorded live at Montreux; the video production of that performance is on YouTube with some great close-ups of Coryell's fingers darting in and out of complex chord structures in split seconds.
If you can find it (I only have it on CD), "Acoustic Reflections" was released in 1976. A nice collection of solo Coryell that was broadcast on radio in Mass.
@spiritofradio - I never played 12 string as I was not even very good at 6 and stopped playing back in the 90's.
