Blimes and Gab “Shellys (It’s Chill)” One of the glories of working in music is the great, feel-good songs that come out of absolutely nowhere — and this track from Blimes and Gab is not only a great, feel-good song that came out of nowhere, it’s a perfect summer song. A tag team of Seattle MC Gifted Gab and San Francisco-bred Blimes Brixton (who describe themselves as “your badass aunties who secure the B.A.G.”), the pair had an earlier single, “Feelin’ It,” featured on “Insecure” and their debut album, “Talk About It,” drops next month.
