Brutalist architecture can be done with good acoustics in mind, it just takes the same sort of planning & design that a non-brutalist building also needs.
The Barbican Centre in the UK is a very famous example of a music (and arts) venue with brutalist architecture, and while its acoustics are considered good but not amazing (or "serviceable", to use the description of conductor Sir Simon Raffle), it could have been much better but its problems weren't caused by being brutalist.

And I really love the Barbican, including how it looks from outside and including how it feels to sing on its biggest stage. An exterior photo: https://www.ansador.co.uk/wp-content/uploads/2020/07/Barbica... And interior example: https://i.pinimg.com/736x/93/1f/52/931f52e58c9b1a2f9330d050a...
