Currently mixing FOH for Nelly Furtado, Jeffrey Luge Holdip has also mixed Citizen Cope, Sophie Ellis Bextor and Santos & Pecadores, as well as numerous reggae projects. Holdip also produces projects out of Kornerstone Studios in Toronto.
The most useful tip I can offer is to keep the lines of communication open with all of the audio departments, including the band. By having positive communication with the band, the source sound can be controlled. On the Nelly Furtado tour, I have been blessed with a phenomenal crew, one that can get all that closer to a great sound. You never know who can supply a great tip to make the show all that much better. If you do not have a crew, make sure that the relationship between the FOH and monitor operator is positive and open. This can make the most difficult of gigs more pleasant.
