At the concert [at the annual "Caecilien-Fest" at Münster in Westphalia] Brahms played his concerto superbly. I especially noted his emphasizing each of those tremendous shakes in the first movement by placing a short rest between the last note of one and the first small note before the next. During those short stops he would lift his hands up high and let them come down on the keys with a force like that of a lion's paw. It was grand.
