Toronto trumpeter Lina Allemano is one of Canada’s most steadfast and consistent voices when it comes to bringing original free-jazz-based music into the world. This month and next, she’s especially busy, with gigs at Montreal’s Resonance Cafe and Ottawa’s GigSpace this weekend followed by more than a dozen gigs in Germany, Austria, Switzerland, Denmark, Belgium and Turkey in late March and next month, thanks to support from the Canada Council for the Arts. On most of these gigs, Allemano will be playing with her group that includes alto saxophonist Brodie West, bassist Andrew Downing and drummer Nick Fraser.
