Let’s all sing “Happy Birthday” to our favorite musical dive, the hi-dive and it’s half-sister, the Sputnik Lounge on South Broadway. The first anniversary party started last night, with a string of killer local bands performing. Tonight it continues; head down for Bright Channel, the Hot IQ’s, Dressy Bessy, Maybellines, and many more. $1 PBR’s will keep the scooter kids happily quenched. They’re starting early – 4 p.m. — so hit this lovely neighborhood joint along your travels tonight.
