Mathias Heise Quadrillion

In 2012, Mathias Heise founded his fusion band Mathias Heise Quadrillion with equally talented peers: Mads Christiansen (guitar), David Vang (bass), and Aksel Stadel Borum (drums) + Mathias himself on chromatic harmonica/keyboards.

Mathias Heise Quadrillion reinvent jazz fusion, having created a completely unique sound combining the chromatic harmonica with new, updated Funk-Rock-Jazz.

Jazz harmonies and improvisation are merged with rock and funk music’s hard-hitting primal beats, and fused into a euphoric, vibrant and very personal expression of sophisticated elegance and accessible grooves.

Mathias Heise Quadrillion have – despite the young age - already played at major festivals worldwide.

The latest album ‘Decadence’ was released in June 2017 as a sequel to their debut album ‘Sudden Ascent’ (2015). The album is produced by Grammy Award winning L.A. producer Erik Zobler, who is known for his longstanding cooperation with George Duke, among many others.

New self-titled album 'QUADRILLION' is set to be released June 3, 2022.

“An ejection of fresh oxygen to the fusion genre”.

“Grab Mathias Heise before he goes to NY to become a star”.

“The band is playing impressively tight”.

“A shining star in the fusion sky”. ____

Rob Mallows (London Jazz News) reviewed MHQ's album launch show at The Spice of Life London, July 2017:

"Showcasing their sophomore release ‘Decadence’, Denmark’s MHQ demonstrated why this band is ripe for solid musical growth over the next few years in a crowded market place of ‘next big things’. Heise and co. demonstrated with their whip-crack group playing and high energy mix of funk, fusion, rock and jazz - what they’re calling FuRoJazz - that they can reach a broad base of jazz consumers. Fresh-faced and with boundless energy, and appealing to the young crossover crowd as well as hardcore jazz-fusion fans, MHQ have the feel of a group destined for bigger stages across Europe in coming years."
