You will be listening to a band called Creepoid on a Sunday. This is the most revealing, yet accurate description which I can give to the sounds you hear in this post. The Philadelphia-based quartet will take you on a short spin throughout the past few decades starting from the 90s melancholia and ending with 60's psychedelic guitar sounds.
They do mix very logically and closely related genres, but the way they've done is what truly distinguishes this band and after abusing on the play button with Sunday, I'll definitely dig into their self-titled album. Until them - time to submerge in those passive-aggressive hippie 90's psychedelia wave sounds, woah!
