The “tapers” section of a 1985 Grateful Dead concert.

Few bands have richer concert histories than the Grateful Dead and Phish. Both bands were always far more successful touring than they ever were in the studio or on the charts. They attracted massive global followings and recordings of their concerts have been traded over the years with the enthusiasm and passion of avid baseball card collectors. Two people who play a key role in that recording history will be speaking tomorrow night at Drexel University’s Stein Auditorium (3215 Market St.) at 6 p.m.

Grateful Dead archivist David Lemieux and Phish archivist Kevin Shapiro are at Drexel for two days of talks and workshops. They have been brought to campus through the University’s College of Media Arts and Design. Lemieux has helped make dozens of Grateful Dead live shows available to the public. He also interacts with a very knowledgable fan base that has grown out the Grateful Dead’s early decision to allow fans at concerts to record their shows. Shapiro has done the same for Phish.

Both archivsts help the bands make decisions about releases and preservation. They will also talk about the impact of digital technology on their work.

A podcast of Lemieux and Shapiro playing and talking about select tracks from shows in Philadelphia will be available online today. The podcast will be available from 3-7 PM as a stream via http://www.drexel.edu/westphal/events/lemieuxshapiropodcast/.
