Question

Can someone explain the last 2 sentences in this paragraph...................................................................Here is one white visitor's account after visiting the Cotton Club as recorded in the New Yorker magazine...the big bass drum boom, booms. enthusiastic sails writhe from the cornet-another flash from two dozen tawny, brown legs, whip-snapping, now hip-twisting, and watch 'em strut! Boom, boom-de-boom boom... .......one by one, our cherished biases are taken off like arctic overcoats. It becomes natural to laugh and shout in the consciousness of an emotional holiday

Answer 1

The Cotton Club was a New York nightclub that featured African-American jazz musicians during the 1930s.

This writer is describing the music and show and how he was enraptured by the whole scene. Apparently he didn't expect to be so enthusastic.
