We're on a long research trip, gathering material for our upcoming travel book on the roots of the blues. Rather than detailed blog posts, we're going to post photos and video bits to show you what we have to do to put a book together. Each photo will have a line or two to tell you what it's about. It all starts with checklists, phone calls, tons of emails and - eventually - a massive spreadsheet that details each day of interviews, museum stops, etc. We leave ... Once out of the snow, Craig really, really, really needs to wash the salt and grime off the Roadtrek ... In tiny Holly Springs, Mississippi we interviewed local blues collector, 90-year-old David Caldwell. His shop is stuffed with 91,000 records (no CDs here) and is so full that you cannot actually go inside. Mr. Caldwell remembers when B.B. King used to play at a Holly Springs venue for a whopping five cent entry fee.

Memphis welcomed us with open arms - we toured Beale Street, the Center for Southern Folklore, the Lorraine Motel, the W.C. Handy home, the Blues Hall of Fame and the Memphis Rock 'n' Soul Museum.

Rigby finally gets her own star ...
