In 2001 that US barometer of affluence, Forbes estimated the annual income of Grateful Dead Enterprises from relic worship – music, merchandise and so on – at $30 million. That is not bad revenue for a band that folded its hand in 1995, making its core members each year a millionaire over and again even without the never-ending cycle of shape-shifting touring. The Road Trips releases are previously untouched relics uploaded from the Grateful Dead memory banks. This one from Municipal Auditorium in Austin, Texas is a particularly interesting one. Keith Godchaux had been newly drafted in as second keyboardist to augment Ron ‘Pigpen’ McKernan. An admirer-punter of the band's music, he had done a crash course in learning the repertoire. With Pigpen hors de combat on health grounds, here Godchaux adds new jazzy sides to their jamming, finding, no easy task, new ways to slide pianistic colours onto a palette dominated by electric guitar and contrapuntal bass melody lines. Sandwiching Marty Robbins’ cowboy flick ‘El Paso’ between two slices of ‘Dark Star’ becomes true chutzpah when they go into unmetered improvisation – jor territory in Hindustani terms. Amid the boogie, blues and shuffle extemporisations of ‘Playing In The Band’, ‘Goin’ Down The Road Feelin’ Bad’, it stands out.
