We are all built for change and evolution, and Kitchener’s Courage My Love is no exception.

These Warped Tour warriors have advanced their sound from feverish guitar-bass-drum pugilism to something more complex, dynamic and striking for their debut InVogue/Warner Music Canada album, Synesthesia. Fans will notice within the very first few bars of “Stereo,” Courage My Love’s incredibly contagious first single, a sumptuous synth hook indicating that twin sisters Mercedes (singer, guitarist) and Phoenix (drums, synth, programming, vocals) Arn-Horn and bass player Brandon Lockwood are pursuing more sophisticated sonics.

“We didn’t want to be stuck underneath a female-fronted rock band ceiling,” Mercedes admits. “We wanted to reach beyond that constraint and see where it would take us.”

Co-produced by David Bendeth (Paramore, Of Mice and Men, Papa Roach) at New Jersey’s House Of Loud and Chris Perry, who also co-manages the band with fellow songwriter and producer Nicole Hughes, – the 11 songs on Synesthesia that were also recorded at Toronto’s Noble Street and Pocket Studios don’t abandon the six-string frenzy or magnetic charm of the earlier two-million YouTube viewed “Bridges”or “Kerosene,” whose video director Emma Higgins was recruited to lens “Stereo.”

Bristling guitar riffs and pounding rhythms still form the backbone of such Synesthesia songs as “Tough Love,” “Need Someone” and “Walls,” but the arrangements are more tenaciously sculptured, with strident melodies and some impressive singing and vocal interplay by Miss Mercedes and Miss Phoenix.

“I want people to look at us and go, those girls are serious songwriters and musicians,” says Phoenix. “We’re 22 and finding out who we are as adults and as people. We want to have our own voice.”
