When trombonists J.J. Johnson and Kai Winding put their quintet together in the mid-1950's, some Jazz critics questioned whether it would work because of the sameness in the sonority of the two horns.
I'm sure glad that J.J. and Kai went ahead with their association and formed a group that produced so much marvelous music as you can hear on the following video.
The rhythm section is Bill Evans, piano, Tommy Williams, bass and Roy Haynes, drums.
