Youtube content creator, CR Guitar, does acoustic guitar re-imagings of video game music. Has a couple other songs & collabs, but the awesome thing about Chris is he plays all parts & layers them together perfectly. Very peaceful & calming tunes - give him a like & a follow.
Barenaked Ladies is a Canadian rock band formed in 1988 in the Toronto suburb of Scarborough, Ontario. One Week is the quintessential Barenaked Ladies song and my first experience with the band. Sticking to a soft rock/folk style, their earlier material is still my favorite, and always a solid choice for when I need to unwind.
Cake is an alternative rock band from Sacramento, California. Classified under multiple "rock" genres (Alt, Country, Experimental, Funk, Indie & Pop), they're kind of all over the place, but easily recognizable. Usually accompanied by keyboard, synths & trumpet, they range from fun to a bit too raunchy, on occasion (Fashion Nugget).
Hootie & the Blowfish is an American rock band formed in Columbia, South Carolina in 1986.
