Hi,
Countless examples ... to the point that many times I can not even remember who that was ... and I likely have the CD/Album for it in my collection.
Of all the hours of the show I have from the 70's, there are probably over 500 bands in there, and since the whole design of the show is not hit radio, sometimes things are mixed in together and sometimes they are not, and the value of the experience of listening to that show increased so much, that it was hard to miss it, and not enjoy it.
It was not about listening to your favorite stuff ... of which you already had the album/CD, either. It was always a new adventure to a new place in a far off distant land ... and one minute I might recognize some Popol Vuh (1st two albums), and the next ... who is that?
I can tell you that I can sit back, and listen to anything ... and remember when I first heard it. For me, there really is no gap per se ... as I still have the appreciation of the guy playing THIRD EAR BAND, right after a PINK FLOYD moment. Or Colin Townes. Or Eberhard Schoenner. Or Vangelis. Or Royale Academia de Musica. Or Uno .... it's hard to remember them all by name ... countless albums, and countless experiences, of the most beautiful kind.
I, personally, don't consider it a gap at all ... I find it a golden moment to blend today, yesterday and hopefully tomorrow, into something new ... a new art ... a new feeling ... a new something or other ... and the artist is my best friend all the time.
... where do you want to be? ...
