There is a fairly new library advertising for composers.
They are looking for the usual genres, cinematic, trailers, Americana, etc, with timed edits and underscores. Standard stuff.
In the ad, they say they will send a brief, to which you submit a cue. If approved, your cue will then be given feedback. Then it is second review,with more feedback, more revisions. Then if ok, presented to client, possibly more revisions. You get 100% of mech and perf royalties, less “a contribution to their costs”.
They OWN the copyright once cue is accepted.
No upfront money.
I would be interested to see what others here think of this(!)
