In a curious Canberra-Estonian hook-up, Sollis discovered that the Estonian composer/astronomer, Urmas Sisask, had visited Australia and particularly Mt Stromlo, during the late 1990s, also observing many Aboriginal rituals in NSW. He later composed a “stellar” piece of music with connections to Aboriginal mythology, and the score was in the package.

Now the ensemble will perform the Australian premiere of Sisask’s “Southern Sky” in the ruins at the observatory, joined by astronomer Fred Watson, who will take audiences on a journey throughout the stars and Aboriginal mythology. The ensemble will later take the concert to Melbourne and Bendigo.

“Southern Sky”, Mt Stromlo, 7.30pm, March 30, dress warmly. In case of rain, the event will be moved inside the Scope Café, single tickets to http://griffyn.iwannaticket.com.au, free for members, visit www.griffynensemble.com
