Just going back a littleton the originality comments, I really like this interview with Goldie on the subject...
Also, a note on transient shaping, swell as tweaking the drums, one of the most useful things I've found with mixing in general is using transient shapers to create a sense of depth to a mix. Our hearing perceives sounds with sharp transient elements to be closer than those with softer transients. This can be manipulated in the mix to create a 'front and back'. For example, you had an acoustic guitar sound and were happy with the volume, you could soften the transient to make it appear further away then enhance the attack thespian to bring it closer. The sampan be achieved with microphone choice if you're recording. This thread is cool Can't think of anything specifically lofi to add, also I did do a session a while back where we ran the lead vocal through a domestic tape deck and sent it back in the computer.... Although it was then quite an edit to restore the timing where the tape seen had fluctuated.
