Last weekend I recorded a rock band all at once, including vocals in the same room. The whole session took 8 hours, including mixing and some "mastering" [slamming the masterbus ]. Overall it sounded pretty solid, and big... maybe a little too much reverb [from bleeding, not digital], but just fine... But in the meantime, I'm working on a symphonic-metal project, where everything is recorded seperately, drums first; with clicktrack. It took us more than 3 weeks, full time, and we're still at mixing stage. Everything is perfect in timing and next-to-perfect in pitch, but the whole project sounds thin and dull, compared to the 8-hours production... I tried to fix things with artificial reverb and delay, both on the induvidual tracks, as on the master- and subbus(es)... But it still lacks some kind of feeling... It is not the playing or the timing; I know sometimes natural tempo-changes are better than a click, but the tempo feels just right... It is pure the sound that bothers me... Any help on this one? Any tips&tricks to get the sound right?
