Being someone who interviews folks for a living, you always have to take everything with a grain of salt. Sometimes you catch someone having a good day, having an emotional day, having a shitty day, and their answers will change, or at least the way they express them will change, day by day, hour to hour.
E-mail interviews (it appears this is one) allow a bit for people to sit and write up and edit their answers, but when you do real interviewing, one on one, via phone or face-to-face, it really depends when you catch the person.
I've done them where I got a heated, passionate exchange from someone, with really pointed answers, which was great, and made a great story. But then a few days later, a colleague from a different publication, speaking to the same artist, got answers that could be viewed in a different light.
