Furthurmore Friday Week 118
Q: In the first half of 1978, there was a major change to the format of Grateful Dead concerts. What was this change?
A: The addition of a defined Rhythm Devils portion of the show in April, 1978 (if people want to be specific, it happened in the 4/6 to 4/12/78 week of shows). Prior to April, 1978, there was usually a short 4-7 minute Drums interlude, but in April, it went on to become the 15-20 minute centerpiece of the second set.
