Aldus looks close, but the bold weight changes the E, so not sure.

Definitely Palatino... something weird going on with the 'G', but definitely Palatino... could it be 'faux' bold?

Well, Palatino has serifs on the centre bar of the ‘E’.
I have to admit the sample looks Zapfish. I thought Aldus as well.

How old is this sample? There were photocompositor versions of Palatino from various vendors.

I don't think it's very old. It's part of a logo for a local rock products company. I'm not sure how long they've been around. I have a hard time believing a company like that would have custom lettering in their logo, but I guess anything is possible. I ended up redrawing the letters using the sample above, and I used Palatino Bold for the subcopy.
