Booking live music acts is a major recurring outlay — tens of thousands of euros a year for smaller venues, and into the millions for the largest venues and festivals — yet the vast majority of those commitments are made without a pre-event, econometric demand-scoring tool like our MLE Score: a fine approach for proven acts, but arbitrary and potentially costly for everything else — emerging acts, untested dates, and even household names whose real pull on this coast is unknown. At €49 — affordable enough to test multiple acts, dates and price points year-round — you get a much better look before you leap.
