Jam sessions came to represent both a way for players to nurish their individual musicianship and a model of democracy. Thus Granz was motivated to articulate his faith in racial justice and transform the ideal into a viable vehicle for challenging segregation, presenting good music and making money. 'As in genuine democracy, only performance counts,' Granz told the NAACP monthly, The Crisis, in 1947. 'Jazz is truely the music of democratic America.'
