If you liked Red Sun in June, you might like Red Valley by Causa Sui as well. According to The Obelisk music news/review website, “Summer Sessions remains a consuming meisterwerk precisely because it manages to capture the warmth and dreamy sensibility so often associated with the hot months of the year,” and this track is one of my favorites from Summer Sessions Vol. 1-3.

According to the More Fuzz music review website/blog, “Song like Waves could easily be the type of song that you’ll want to hear on the grass on a bright and sunny day!”
