The click is essential today because of plug and play and diy's and daw's.

If you're gonna have other musicians play parts for you, they cant play after your part is done, they need to be playing at the same time. so when not playing at same time the click essential, but it also makes the music not nessecarily bad, but not "live" sounding. For rock music, live sounding is what your should be striving for.

For pop...or singer songwriter stuff, the new way is probably ok.

BTW, how does a drummer push or pull back behind a click, when the other instruments are doing something else. generally drummers play with a click in one ear, and a reference track in the other
ear, but the reference track is generated via a click track as well.

Now what do you mean about using all human feel in BIAB?

How is that done, Im not crazy about "humanizing" effects, they just create random flucuations but not
human ones.

When a drummer slows down, the rest of the band tends to adjust their timing, then when the bass player is behind, the drummer catches him, often without even realizing it, they just find themselves because the song structure mandates it.

Cant beat a real band, real band doesnt come close, but looking at what is out there, it might be the best there is.
