I imagine most people here already read Endless Summer Quarterly, however, the new issue arrived right in sync with the release of Sunshine Tomorrow. It's all about Smiley Smile, with new interviews with both Brian & Mike. Also has a great section on the new release, featuring interviews with Howie, Alan & Mark. Between the excellent c.d. liner booklet and this, it's fantastic to have so much to read on breaks from listening.
