Acid house enthusiasts (the music, not the drug or the book) should get down to Smartbar tonight where the lineup is all acid house, all night long. DJ Pierre, the man who discovered that tweaking the bass of the TB-303 drum machine produces the unique squelchy sound that came to be known as acid, is headlining. Adonis, Mike Dearborn, and Tim Baker are also on the lineup. 3730 N. Clark, 21+, 10 p.m., $10.
