Yesterday has an idiomatic usage which is basically a synonym for "as soon as possible".
I need those reports, and I need them yesterday. ≈ I need them ASAP.
We want to see them in a concert. Bring them for a live yesterday!
Can "hier" be used with a similar meaning?
E.g. does
On veut les voir en concert. Amenez-les pour un concert hier!
sound idiomatic?
