Putting Briggan Krauss and Skerik on the same stage sounds less like a meeting of peanut butter and chocolate and more like a collision of Pop Rocks and Hot Tamales. Definitely a mouthful, but will these two great tastes taste great together? If anyone can make it work, its Zony Mash, one of Wayne Horvitzs longest-running Seattle units, which was born under the viaduct at the old OK Hotel and has reared its head on an unpredictable schedule in the years since. Combining swamp funk, Fillmore jams, and country ballads, Zony Mash is a quartet at heart, with the always-brilliant Tim Young on guitar. But Horvitz fills out the front line with horns on festive occasions. As the band heads out this week for a few European shows, its got a full lineup, with trombonist Steve Moore and a pair of tenor saxophones: Krauss, a fierce animatronic improviser, and Skerik, an equally powerful, but more soul-grounded player.
