Loved this puzzle! Nice grid of double triple stacks, varied and smooth fill, and novel clues! Now to check out your series of Iceland posts before you change the name of the blog!
This was great! I've been a deadhead for a LONG time now, so Garcia, Weir, Lesh, et al. all appeared in my head and now they're singing and playing music. One small thing, Faraday was in electromagnetism, looks like you might have the n and the e switched. Thanks again!
