Math rock music fans converge on Yuyintang Park with a sexy, sonically stimulating trio of math rock bands who approach the genre in distinctive ways. Diels-Alder, the math rock-inflicted, emo rockers bring conviction to their music - a testament to both their crisp songwriting - which appeals to the band’s pop sensibilities - and their elastic, playful musicality. Meanwhile, Shaoxing math rock act Chocolate Factory brings a more steady hand to their smooth yet invigorating sound. And representing Shanghai are sincere up-and-comers Zhuyouhui and Da Seven, who bring an underground lounge room jazz approach to math rock - turning what could have easily been mellow jams sessions into elaborate off-kilter arrangements chock full of offbeat time signatures and robust musicality that’ll have your head spinning. Yeah, time to geek out with our hearts out.
