When introduced, bop was as unpopular as swing had been popular. The complexity of the style often left the audience behind. The funky players were interested in recapturing the audience and reestablishing the hot jazz expression that had been abandoned by the cool style. This return was enthusiastic and reached back to the most communicative music in their past- church music. Another motive, less defined and certainly debatable, was the need to reclaim jazz as a predominantly African-American expression. Cool, and particularly West Coast jazz, was predominantly white even though Davis and Young were the forerunners. The structured, soft-spoken arrangements were certainly more typical of the European tradition than the expressive African-American voice heard in the early blues.
