Gabriel Mark Hasselbach unabashedly embraces Contemporary/Smooth and Mainstream/Classic jazz, as a succinct and lyrical trumpeter, flugelhornist, and flautist, with mad skills across the wide jazz spectrum (he also plays valve ‘bone, electronic valve instrument, and sings!). He has 15 critically acclaimed albums under his name (and many more with others), 11 certified Contemporary Jazz Billboard hits, several JazzWeek hits, several JUNO Awards, a West Coast Music Award, and Album of the Year and Instrumentalist of the Year at the 2011 Canadian Smooth Jazz Awards.

Gabriel has charted on mainstream and contemporary charts, and feels that both formats have emotional, intellectual, and artistic merit. He has performed at festivals all over the world, including Montreux (Switzerland), North Sea (Netherlands), Portugal, Tokyo, Mexico, Singapore, French Quarter Fest (New Orleans), Vancouver International Jazz Fest, Australia Expo, Kuala Lumpur Jazz Fest, at the 2008 Beijing Olympics, and even in the home of Bill Gates.

He has performed and/or recorded with well-known Mainstream artists such as the late Larry Coryell, Ernie Watts, Bob James, Bob Mintzer, Cory Weeds, Jeremy Monteiro, and Contemporary artists such as Jeff Lorber, Paul Brown, Paul Hardcastle, Bob Baldwin, Marc Antoine, Greg Manning, Darren Rahn, Warren Hill, Rob Tardik, Rock Hendricks, Tony Saunders, the late greats Chuck Loeb and Larry Coryell, plus Gino Vanelli and Michael Bublé (recording several albums with the latter).
