prize17-5, Exercise 3: The Goodman trio and quartet

Model answer (check the details):

Why they mattered: Teddy Wilson, and later Lionel Hampton, both Black musicians, played with Goodman and Gene Krupa on stage and on radio, in front of mixed audiences. They were among the first prominent integrated jazz groups, and certainly among the best known, which made the sight and sound of a mixed band familiar to a national audience.

What they did not change: they were not the first integrated group in jazz, and the wider rules of segregation stayed in place. Hotels, venues and much of American life remained divided, and the musicians still met those barriers when travelling. The groups were a visible but partial step.

Care: avoid "the first". Say "among the first" or "the best known", and put the limits next to the achievement.
