The Grateful Dead are going on tour this spring, and I’m torn about whether to see them. Seeing bands who are past their prime can have its rewards, but it can also leave a taint on some fond memories. (A lot of fond memories, in this case.)

Your advice, please?

But first, take a look at these videos the band released of the four surviving members talking about their musical process, particularly the one titled “time in the groove,” in which they talk about musical improvisation. (Sorry, I can’t embed.)

I like the bit where they’re working out “Help on the Way/Slipknot,” and the small bit of St. Stephen that they play does sound kind of nice…
