An annual Halifax Music Co-op concert series performed by a slew of local artists and composers, HMC's Inventions creates a world of diverse, textured sound for you to get lost in. This year Shelder the Electric Clamfish ("folk-punk Canadiana") and Jont & the Infinite Possibility ("expressive pop") are teaming up with the HMC Orchestra and HMC's Big Choir for what's sure to live up to its billing as "three nights of earth-shattering world premieres."
