With only one more week on Yuyuan’s Specters live-music-o-meter, the rock and roll safe haven is ratcheting up the noise with a string of rollicking shows. Tonight features jangly indie rockers Fulcrum, who canvas across shoegaze, psych rock, and anthemic Britpop with conviction; as well as crunchy power trio Doppler Drive, Buddha Beat, and finally, Rage Against the Machine aficionados Riot Symphony, looking to capture the ‘gritty energy of 90's grunge and the raw intensity of Nu metal’.
