Ravel made only one visit to Czechoslovakia. During his European tour in the early part of 1932 (February?), Prague was one of the cities to which he brought his newly completed Piano concerto in G.
As soon as he arrived, Ravel caused some consternation to his soloist Marguerite Long by insisting on going on a shopping expedition in spite of the the concert which they had to perform that evening. He wanted to find a particular kind of bottle as a present to take back for his old friend Mme Fernand Dreyfus. He and Marguerite Long searched all over the city before finding what he wanted, and they returned in a state of exhaustion, she highly anxious, he quite delighted by his achievement. (Long  p.67-68.)
