The GRIFT is playing in General Stark's pub on Saturday Feb 23, 2013, starting at 4PM.
I haven't seen it advertised anywhere, except on the MRG website where it is buried under the "Visiting" menu, and on the GRIFT's website.

Let's all spread the word and come in for a good time, as MRG doesn't seem to be all that interested in telling us much about what's going on in the pub anymore. We need to avoid another Valentine's day disaster when The GRIFT played at the Harpoon apres ski party that was never advertised anywhere and attended mostly by employees.
