Yeah, you'd be surprised. Sometimes a "big name" producer will sell records just for the name, but often feel the label name is even more responsible than the artist sometimes.

The fact is, we all know techno sales are in the shitter, and many big name techno DJs pockets' are wearing thin.

At the end of the day if some popular techno artist puts out a shitty record it will still sell, but not as good as one of their "hits."
Instead of selling maybe 6,000 of their hit, this shitty record with their name will sell say...2 or 3,000.

I can think of a few swedish guys who gave some tracks to American labels. These swedish guys usually push about 4,000 records, I am not even sure if their u.s. releases pushed 1,500+ records...and its because the tracks sucked. (And no, I'm not thinking about Headroom)
