At the few early scores of John Williams that I own, I am mostly struggling with NIGHTWATCH. I enjoy it for about 10 minutes, but then it becomes a little annoying.
Almost similar with TIME TUNNEL. Great main theme, but the pilot episode score is in the long run a little very Avantgarde and dissonant.
It’s a bit rough and tough, yes. I find that certain bits of LOST IN SPACE are even tougher than TIME TUNNEL or NIGHTWATCH — there’s a lot of this.
But the toughest bits that Williams wrote for TV are not released commercially. Like the episode “The Machine That Played God” in KRAFT SUSPENSE THEATER, with its wild dissonance and even early synths. I play a clip from this in the webcast series, albeit in terrible sound quality.
