L-Acoustics Shines at Adelaide’s Summer Sounds Festival 2021 Australia – South Australia’s Summer Sounds Festival was a four-week outdoor concert series offering the joy of live sound to a 2,100-capacity audience. Eighteen shows ran the whole month of January, with festival-goers safely and comfortably spaced in ‘Party Pods’ that accommodated four to six people each. The festival celebrated Australian artistes such as Bernard Fanning, Spiderbait, and Hayden James. Through the collaboration of Five Four Entertainment, Groove Events, and Secret Sounds, the festival promoters looked to Adelaide-based L-Acoustics rental network partner Novatech to provide that dynamic live sound festival-goers have been craving.
