I share your preference for mixed rep shows, but I just want to say that Russell and Stowell produced many of those as well.
I did not mean to imply that Boal has a higher percentage of mixed vs full length programs. Indeed, I wouldn't be surprised if the statistics show that Stowell/Russell did a higher
percentage of mixed compared to Boal; however Boal has definitely programmed differently than the years prior to 2005........and I prefer his programming to that of the past. (I likely gave you the wrong impression by making my comment as the last sentence of a paragraph on mixed vs full; I should have made a new and separate paragraph out of that comment.)
As I remember, the easy majority of the Stowell/Russell programs were
mixed rep, but those mixed programs did not range over as wide a field as does Boal's. Many, many of Stowell/Russell programs contained mostly Balanchine and Stowell mixtures with the occasional well known names in choreography thrown in (e.g., Tetley, Petipa, Martins). There was a certain "consistency" IMO to the Stowell/Russell programming......a consistency that the audience was lulled into expecting. Don't get me wrong, I am one for sure who can never get enough of Mr B so I'm not complaining about that, but I do prefer the more wide ranging pieces that Boal has brought to our audience; and I also think his choices have greatly increased the skill set of our dancers (especially in the acting and dramatic power departments).
Of course, none of this would be even remotely possible without the heroic work that Stowell and Russell did over 25 years to build PNB into the thoroughbred that Boal is now riding.
