Montcalm was a shortlived band somewhen between 2003 and 2004 with Ampere's vocalist Stephen Pierce on the guitars and vocals. They released a demo and two splits with Deadseraphim (four songs from the demo) and The Kodan Armada. I haven't found an actual picture of the band, sorry.
I think at some parts there are some similarities between Ampere's sound and Montcalm's sound. But other than that, I think there's something more to Montcalm. I'd say every song is different in its own, you'll get influences from Moss Icon to Saetia to Indian Summer and so on. Listen for yourself, you won't be disappointed.
