With so many situations that eschew wedges in favor of in-ear monitors and recording sessions taking place in non-conventional settings, I always bring some “ears” to gigs. You cannot count on every venue to provide some “cans” or “buds.” Have your own set at the ready.
I was hired for a session by an artist that was recording on a laptop studio. Just before I left my home, I noticed my headphone extension cable coiled on a stand. I decided that it would not be needed.
To my dismay, the artist/engineer had brought only one set of headphones to the session. Good thing that I had my set… but that extension would have sure come in handy.
Always bring the ears…and maybe an extension.
