Ideas on how to add interest to Guitar and Voice song I'm recording a couple of songs for a local singer songwriter shortly. She's singing one original and one cover. I've got a fair bit of creative freedom for this, so I'm looking for ideas on how to add interest. I know this is as much arrangement as audio engineering, but the singer has given me this creative freedom. She just wants to sound as good as possible.

She's a great singer, but guitar and vocals isn't a super exciting sound. I'm planning on double tracking guitar and panning. I'm also considering doing the same for vocals on choruses. I may also add in some light percussion as well.

Any other ideas?
