Tonight at the Portland Art Museum, local Grateful Dead tribute act Garcia Birthday Band will try to recreate a lost Dead show from 1967 using research done by a Portland State University graduate student.

You can read Brandon Widder's very thorough feature about the "Turn On Your Lovelight" show, named for a Dead song that may well have been played live for the first time that night, right here.

But—and this is a little freaky—that's not the only Turn On Your Lovelight-related news this week. Eugene's Chez Ray, once the Dead's touring chef, just announced a new line of coffees, including Turn On Your Love Lite Roast.

We're not sure about the ground stuff, but all the marketing material is a delight: "With each organic sip lives the authentic story of the 60's San Francisco trip. Feel the family! "Chez Ray's Headliners' Organic Coffee™, It'll Roast Your Bean."

The show starts at 7 pm, with a set from the band that opened the original show, Portland's US Cadenza, which reunited for the occasion.
