I don't follow online interviews much, as there's a lot of garbage, chaff and pointless chatter. I do check the interviews on d-m though, which involve smaller bands and ask them interesting questions...
would you consider interviewing doom record labels? I'd love to read a bit about the people behind iHate, black tears, psychedoomelic and shadow kingdom for example...
If I remember correctly, the interviews are part of a second book project by Aleks Evdokimov... I think the best thing to do would be to send a PM to Mike, aka endemoniada...
