About Intervals:
https://intrvls.com
It's been an interesting journey for Canadian progressive metal outfit Intervals. After building a diehard fanbase with their purely instrumental jams, the group added a vocalist to the mix for 2013's A Voice Within - a move that proved divisive for both the band and its followers. It was short-lived, however - in 2015 Intervals returned to its roots, thrilling fans with the instrumental album The Shape of Colour. Throughout the band's various incarnations guitarist and founder Aaron Marshall has remained a constant, and his insane fretwork and stylistic fluidity continue to be hallmarks of the band's live shows. Marshall and his band tear through genres a mile a minute in concert, adding a hard-hitting metal edge to everything from funk and jazz to psychedelic rock. The band's talented rhythm section is airtight, but Marshall's virtuosic shredding is the real star of the show, and his ability to make the guitar sing pushes the band's instrumental jams to the limit.
