Correção de texto "Villani got up...''

Villani got up and headed for the piano, to illustrate what he was saying. That reminded me not only of those vigorous and eccentric ostinatos that Arrigo Barnabé used to insert in his music just about at the same time, but also of Villa-Lobos, in whose pieces there are also ostinatos which are not so easily labeled.

N'ao seria melhor demonstrate?
Justa about at that same time= more or less at that same period of time....ou in time?
