I usually have my drums routed to a group channel (not as a send but as an actual group channel) with some soft clipping and light compression just to pull it all together, but actually putting them on a SEND to some hard compression, to get a parallel mix going on, is very good advice for added punch, I've done it on some older mixes with varied success, but after sticking at it I'm becoming more confident with the practice and using it to great effect on a few client's mixes at the moment. Really good stuff here as usual Ola. Me love you long time!
