PINNACLE DUO
An exclusive live music experience by Australian Idol’s Sash Seabourne and Bec Voysey.
Our Story
Pinnacle Duo is an acoustic live music act delivering refined and artistically arranged live music for weddings and events in Perth WA and beyond.
Brought together through the Channel 7 series Australian Idol, Sash Seabourne and Bec Voysey found a natural musical chemistry that now forms the heart of each performance.
The Journey
Born and raised in Western Australia, our story began on the iconic stage of Australian Idol in 2023.
What followed was an extraordinary journey to the live show finals, high stakes, long days on set, and an intensity that we’d never felt before. For us, it was transformative. Amid the pressure, something rare emerged: a profound connection and a musical chemistry defined by mutual respect for artistry.
From the moment we wrapped up the show, Pinnacle Duo was born; a name synonymous with elegance, passion, and striking performances.
See where it all began, in our original audition tapes below.
“We had Sash & Bec perform at our wedding at Cooee and they were absolutely incredible! Their set list options were a great mix that suited the vibe of our entire day perfectly.
They were extremely easy to communicate and organise everything with, which made the whole process stress-free. We had so many compliments from our guests about how talented they were. My husband and I would highly recommend them for any special event. Thanks Team!”
-Georgia & Mick
Love Letters, from our couples
“Pinnacle Duo were absolutely amazing at our wedding and truly exceeded all of our expectations. From start to finish, Bec & Sash created the most beautiful atmosphere, perfectly setting the tone for our day and evening. We received so much positive feedback from our guests, many of whom commented on how incredible the music was. Sash was on the DJ decks at night time and everyone had a blast! He knew exactly how to read the room. We couldn’t have asked for anything better and would highly recommend Pinnacle Duo to anyone looking to give their wedding day a magical touch.”
-Sophie & Brock
“We couldn’t recommend Pinnacle Acoustic Duo more! Sash and Bec created such a beautiful atmosphere on our wedding day; the ceremony and cocktail hours sounded incredible.
They went above and beyond by learning and creating a tailored acoustic version for our aisle song, and even took extra time with me to plan the walk down the aisle so the chorus would be perfectly timed. Their professionalism, talent, and friendly energy made the day feel relaxed and special, and we had many guests comment on how great the music was.
It was such a pleasure having them as part of our wedding! Everything ran smoothly, and they really added to the magic of the day.”
-Caroline & Owen
