At this point it may be good to clarify what we mean by "tension," because the term is cropping up here in wildly different contexts.
To me, Horowitz does not look tense at all. He is which is not the same thing. He is highly focused. To be that focused, you cannot be tense. Tension would distract you from that focus, diverting your energy into other, less productive channels. The quality of Horowitz's intensity is the antithesis of inhibiting physical tension as we know it.
The mistake we all make is to try to create that intensity through physical tension. It just doesn't work.
Musical tension is something else altogether. For instance, rhythm and melody are often at odds with each other. Rhythmic vitality generally wants to surge forward wheras melodic singing generally wants to lengthen each note to get maximum "juice" out of it. When we remain aware of these opposing forces, both completely valid and necessary, we can create kind of alchemcal synthesis whereby their struggle creates an incredible musical tension or focus. This is a very good thing! This is what makes music grip us and prevents it from being flat and insipid.
There are many of these contradictory dichotomies in music, I only take rhythm and melody as one prime example. There should always be at least one or more of them operational in performance, that's what gives the performance meaning and intensity.
