Well, in rock or metal, drums define acoustic space of entire track.
Basic thing to capture it is miking technique. You can get pro sound with 6 mics :
2 overheads - condenser cardiod to capture full stereo details
1 kick mic - AKG D112,
ElectroVoice RE20 or similar
1 snare mic - Shure SM57
2 tom mics in x-y ( crossed pair ) configuration between toms
With this setup you will catch natural stereo of drum kit.
Panning is essentiall - pan overheads hard left and right, kick centre, snare bit right, and x-y pair half left and half right - check in mono to avoid accidental phase cancelations.
Then record bass like i described in Using Fundamental FREQ... Thread. Use fattening technique on bass track - original left, delayed right, stereo compressed.
Record guitar with at least Shure SM57, positioned at centre of speaker cone. Record it twice and pan hard left and right - you get classic Wall Of Sound Guitar.
Try to record two speaker cabs driven by a single amp - two cabs with two mics under some angle in same room - natural stereo.
Or record stereo cabinet with M-S technique.
Separation and definition are question of psychoacoustic space encoded in sound, not only freq ranges.
That is why old Elvis or Beatles recordings still sounds good today - and everything is done without plug-ins
Mixing is more philosophy than tecnology. Wow
