This Saturday is the 4th edition of Don Audio Showcase Sessions at the Brickhouse Brewery in Patchogue.

Brickhouse has a big stage that is home to cover bands, jams, and singer-songwriters alike. This Saturday, original bands Butcher’s Blind, Everything Grey, and the Chris P. Cauley Collective will take the stage. These acts are complementary, but I wouldn’t necessarily call them similar.

Everything Grey mixes a great classic rock sound with new songs and twins Allie and Jacquie Lee sharing the lead vocals (this leads to some pretty awesome harmonies). The band sounds both big and well-put-together, a good combination.

Butcher’s Blind, a Queens band who just came out with a new CD released through Long Island’s Paradiddle Records, brings simple, elegant folk rock tunes that would be equally appropriate at Woodstock in 1969, or a hip Manhattan coffeeshop in 2012.

Chris P. Cauley Collective is the big fat band sound that now belongs to Chris P. Cauley. Many may remember him for his solo/acoustic performances around the usual singer/songwriter haunts. What you might not know about him is that he’s been self-recording and self-releasing lush EPs and albums since 2007. The Collective sounds a little more like this vision fully realized in a live setting.

What else do you know about this Saturday’s show? Well, it’s a $5 cover to get in and there’s a lot of good beer on tap. Starts at 9 and ends “whenever,” as is usuallly the case with these big fun shows at Brickhouse. The Brewery is located at 67 W. Main St.
