He has an intuitive understanding of where a band are within the industry, and provides really practical advice and achievable goals to reach towards. For us, it give us the direction and focus we needed to progress forward at a pace that we’re comfortable with.”

Simon Panrucker

“When I met with Brett I was at a crossroads in my career with a hundred directions and I wasn’t sure which one to choose. Brett was able to patiently and thoroughly map out all the areas of my career and like a tree-surgeon swiftly cut away the dead branches, identified which interests and needs fed into others, and before long had identified the main branch upon which to focus all my energy for the next year. Before our meeting I felt like a hot pan with popcorn bursting in every direction, but now I know which bag to put all my sweet nuggets into and I can’t wait to get going!”

Hal Wheeler, Arrival Sound System

“Having worked with Brett Leboff for more than three years as a manager/coach/adviser. I can state that he has got a very lucid overview of the music business AND the challenges of artists. We are naturally impatient about transmitting our art to the outside world and I find Brett is excellent in explaining and guiding me through the complicated, twists, hard labour and on to the clear path to success!”
