When Derek Coller decided to pay tribute to his late friend - the author, biographer, discographer and researcher, Bert Whyatt - he looked for a common theme under which to group some of the articles they had written together over the years. He found it in Chicago where their research activities had gravitated towards the style of music created by the young white musicians from that city and its environs - particularly those who rallied around the figurehead of Eddie Condon - as they listened to and learned from the pioneer black stylists, many of them the greatest jazz players to emigrate from New Orleans, including King Oliver, Louis Armstrong, Johnny and Baby Dodds and Jimmy Noone. Two trips to the USA, made by the authors in 1979 and 1992, led to meetings and correspondence with some of the musicians in this compilation, and to learning about many others. There are connections between most of these articles, interviews and notes, with an over-lapping of jobs, leaders and clubs. Some of the stories are about pioneers: Elmer Schoebel, Jack Pettis and Frank Snyder, for example, were in the New Orleans Rhythm Kings in 1923. Trombonist George Brunis, chronicled here, was also a member of that band, though his long career - during which he played with Muggsy Spanier, as did Rod Cless and George Zack, in the Spanier Ragtime Band of 'Great Sixteen' fame - has been more widely documented. Floyd Bean and Tut Soper, here too, were also Spanier alumni. The articles originally appeared variously under a dual by-line, or by either Whyatt or Coller, but always with consultation and discussion prior to publication. Here they become a lively mix of the voices of the authors as well as the musicians and their families, building a story through biography, reviews and discography. The book is illustrated with evocative black and white photographs and images, and there is an Index of names and places to help the reader keep track of the musicians, composers, producers, promoters and writers who created this part of the history of jazz.
