February 4, 1969: The Music Box, Omaha, NB: The Grateful Dead/Liberation Blues Band
The Music Box was at 118 N. 19th Street, at the edge of Omaha's Old Market district. The Old Market had been the business center of town in the early 20th century, but by mid-century it had become a sort of arty warehouse district. According to various commenters on the Archive, the Music Box was a tiny place, with a capacity of 500 at most.
The Grateful Dead actually played the Music Box twice, once in February and again on April 15, a few months later. Both the February 4 and April 15 shows were on a Tuesday night, and that was not at all a coincidence. It's important to understand why the Dead would play such tiny places, far from major cities. The Dead had had a big weekend booking in Chicago, and then a Sunday night in Minneapolis. They had shows coming up in Kansas City, St. Louis and Pittsburgh on Wednesday, Thursday and Friday (Feb 5-6-7). Yet they had to stay somewhere on Sunday, Monday and Tuesday nights. By playing a club in Omaha and earning a few bucks, the band could cover their traveling and road expenses for those few days. If they didn't play the show, the band would still have had pretty much the same expenses.
Omaha was about 2/3 of the way from Minneapolis to Kansas City. Whether the band flew or drove, it was easy traveling (I-35 to Des Moines, W on I-80 to Omaha, then I-29 to KC). Places like Omaha, Minneapolis, Kansas City or Salt Lake City got a lot of good shows because they were conveniently located between major stops on the growing rock circuit. Today, everywhere is on the rock circuit, but when it was just getting started in the 1960s, only the major cities had really attractive bookings. However, the cities in between them had an opportunity to get some shows, and in return hard touring bands like the Dead (and The Byrds, Savoy Brown, Ten Years After and dozens of others) had a chance to build a loyal audience.
