WHY: SoMa’s Twitter/Zynga/Facebook era pushes a bleeding-edge movement of bits, bytes and tweets but stifles the physical movement of its hardworking purveyors. The local vanguards of Tech Bubble 2.0 are tethered to ergonomic workstations in a kinder, gentler version of Apple’s “1984” ad. Catered meals are consumed at desks, spouses and children corralled into onsite lifepods and programmers’ muscles atrophy below the waist as their monitors and business briefs get bigger and bulkier.Clearly, these poor enslaved automatons need some Beats for Lunch. WHAT: BEATS FOR LUNCH (fka RECESS), the new midday dance party brought to you by the merry pranksters at SunsetSF (Sea of Dreams, Silent Frisco, SF Funk Fest), aims squarely at the lethargic routines of round-bellied office workers and delirious dot-commers, prompting them to get ready to get sweaty and dance…during the lunch hour.
