Mixology Monday, the brainchild of spirits writer Paul Clarke, is more pow wow than throw down. It's an online cocktail party that invites bartenders, boozehounds, and bloggers to create drinks that adhere to a central theme, chosen by that month's host. Past challenges have spun on spirits ("Vodka is Your Friend") and sentiments ("Hard Drinks for Hard Times"), but now, thanks to Cask Strength's Andrew Bohrer, they've taken on a patron saint: Tom Waits.

"His body of work spans 40 years of songs that take place in bars," writes Bohrer in his announcement of the challenge. "Every bartender has a love and a mind to switch over the tunes to Waits for the late night closing hours." And indeed the mixologists answered the bell -- cocktail creators from Seattle to London have designed drinks that speak and sing, ache and rumble, all in honor of the soaking soul's finest troubadour.
