BoA’s US album disappoints by Philip Gowman posted 16 Aug 20098 Dec 2017 updated 8 Dec 2017 in Music. 1 minute read Oh dear. I thought BoA’s US album was going to be a bit better than that. If you have to use a vocoder to make it in America, stay in Asia. #. I suppose the sound production is geared towards a US market. Shame.
