I'm familiar with a few of them, should check out the others. I would argue that AvB and A&B are pretty popular/well known though. My one friend who's an EDM maniac claims AvB has gotten very stale over the years but I don't notice/care - he has lots of great stuff. "This Light Between Us" was a wonderful song/video.
Intense was a huge step up from Mirage. And yeah they're both well known indeed, but on a site like this that seems to cover only the biggest or the ones hitting the charts, i'd appreciate more coverage. as for A&B, have you heard their album Sirens of the Sea
as OceanLab? It's fantastic, and I'd be confident enough to recommend it to anyone on here at all.
