A UNIQUE instrument will help a musician launch her new album with a concert at the home of Sharmanka Kinetic Theatre.

Gayle Brogan will play a sonic sculpture named the Aeolian Chimes at the live launch of Celestial Navigations, her 15th album under her alter-ego Pefkin.

The gig at Sharmanka, Glasgow, home of the extraordinary mechanical sculptures of Russian artist Eduard Bersudsky, will involve the Ayrshire-based musician coaxing sounds from the piece, which was created from a copper bowl and clock by Stromness-based metalworker Fiona Sanderson.

The Pefkin show marks a decade of live performance events at Sharmanka, which this year celebrates 25 years of being based in Scotland.

Brogan has been making music for around the same time, first as a founder member of retro-futurist duo Electroscope, then under her Pefkin alias, as well as being a member of umpteen other projects including Burd Ellen, her striking duo with Debbie Armour.

Those venturing to the launch of Celestial Navigations, which covers subjects such as Orkney-born Arctic explorer John Rae, Inuit creation myths and the Northern Lights, can expect, according to organisers, “longform drone that will deliver you into the heart of the aurora!”
