周蕙美嗓動人，明（24）日起一連2天登高雄衛武營歌劇院帶來「大玩樂家3 小蟲&簡文彬&周蕙 跨樂衛武營音樂會」，然而她演出前大病了1個多月，鼻涕倒流、濃痰塞滿喉嚨，聲帶肌肉更是紅腫，昨記者會上她仍未完全康復，直呼這陣子心情像雲霄飛車。
周蕙首度跨界古典樂，演繹小蟲的13首經典作品，包括「小雨來得正是時候」、「我可以抱你嗎」等，周蕙形容自己是「千面女郎」，為了這場演唱會，她投入的心力更勝以往，甚至比準備5月的個唱還要緊張，笑說經紀人原本想要推掉，但她很堅持，「因為這個機會真的太難得，流行歌手很難有機會登上衛武營歌劇院。」
她認為此次「大魔王」是潘越雲的「我是不是你最疼愛的人」，因歌曲慢到幾乎沒有節拍，「我的耳朵必須非常專注，很擔心會搶拍。broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.」其實她更擔心唱一半開始咳嗽，若真的發生，笑說歌迷會聽到「期間限定版」。
周蕙原本就有過敏性鼻炎，1月底染上感冒後，她連忙要公司除了除夕特別節目，別排其他工作；前陣子她檢查聲帶，好在一切無事，只是肌肉很紅，她很怕會像之前一樣出現失聲慘況，表示不敢打類固醇，加上醫生用藥小心，前陣子她忍不住下最後通牒，請醫師開重一點的藥。
周蕙的歌聲高亢清亮，打動許多人的心。圖／衛武營國家藝術文化中心／陳建豪提供
