Grant Richard Kwiecinski (born May 31, 1990), also known by his stage name GRiZ, is an American DJ, songwriter, and electronic music producer from Southfield, Michigan.

After growing up on big horn sounds of funk groups like The Meters, Kwiecinski found himself gravitating towards that influence when he first began making his own music in college.

[1] Following such success, GRiZ released six more albums, Mad Liberation in 2012, Rebel Era in 2013, Say It Loud in 2015, Good Will Prevail in 2016, Ride Waves in 2019, and Rainbow Brain in 2021.

All Good Records describes itself as a label that "reps old school motown soul, future funk, new disco, cutting edge electronica, and anything on the forefront of new sound.

During the twelve days leading up to his annual two-day festival in Detroit called GRiZMAS, all proceeds generated from events are donated to a variety of charities, and fans are often rewarded for their participation.

The initiative found the Boulder-based artist leading a 12-day series of charitable activities in his hometown, from collecting coats for the homeless and bringing supplies to dog shelters to spreading Christmas cheer throughout the economically depressed city via free shows, industry panels and a "Night Before GRiZMAS" benefit warehouse concert.
