但是直到2005年1月下旬才开始音乐活动。世文和赛门两兄弟是加拿大人，但是他们认为自己是一支北京乐队，并且至今为止的演出都是在中国。他们的风格跨度从沉重的低保真循环到梦想的shoegaze。有时二个音符比十二个好，有时没有音符比二个音符好。在2006年12月，热和冷在“白色”乐队的张守望和沈静的鼓励下，重新振奋并开始表演。 随后的2007年夏天，他们做了大量的演出。热和冷也和实验／朋克／灵魂乐队Fear the Talon，即兴／drone团体“说中文或者死！”，concrete独奏／集体表演3951等一起或分开表演。

Hot and Cold was formed in 1991 but only began playing music late January 2005.While brothers Joshua and Simon are Canadian, they consider themselves a Beijing band and have performed exclusively in China.Their style varies from thrashing lo-fi loops to dreamy shoegaze. Sometimes two notes are better than twelve. Sometimes no notes are better than two. In December 2006, Hot and Cold reunited and performed at the encouragement of White's Zhang Shouwang and Shen Jing. They followed up with numerous performances during the summer of 2007.Hot and Cold also play together and apart in experimental/punk/soul outfit Fear the Talon, improv- drone group Speak Chinese or Die! and the concrete solo/collective act 3951.
