If you haven’t already seen the multiple Facebook event posts out there about this party, consider this your notice. A collection of heads from the mid-nineties heyday of Chicago “rave” have returned for another in the series of Come2Gether revival events, this time at the Mid. Featuring a trio of headliners (McBride, Johnson, Hyperactive) and a lineup of mainstays from the era (Vega, Werner), this promises to be a blast from your big-pants past. Get your whistle on!
