We know they have a long history, they obviously work well together and they made U2's best albums.
But - do you think it's possible for U2 to make a great non Eno/Lanois album (some would argue War is great) ? What would their output be without them? Do you think U2 needs them to survive the years and is the collaboration getting predictable by now ? (they brought them after the first three albums to change their sound, again with JT to visit America, AB to get out of the 80's, later with ATYCLB to get out of the 90's and it seems like they're getting ready to leave the 00's and change their sound again with them)
