.Dear Diary

After a brief hiatus and the departure of two members, Cotati’s much-heralded the Rum Diary returns to the postrock scene with a headlining appearance at the Mission Creek Music & Arts Festival, the grassroots version of Noise Pop. About the now-trio’s in-progress new album, Daniel McKenzie says the vocals and basslines will be in line with past releases, but the addition of drummer and multi-instrumentalist Jake Krohn will be the biggest difference. “Without getting too electro on everyone, we are trying to introduce some interesting digital elements to the songs,” McKenzie wrote in a recent e-mail. Also thrown into the mix are the members’ side-projects: McKenzie’s ambient electronic work and Jon Fee’s acoustic Americana musings. Check them out with French Disco and Empty Rooms at the Hemlock Tavern on Friday, May 11. 9:30 p.m., $7. HemlockTavern.com
