This year, the Oakland-based music group Alphabet Rockers was nominated for a Grammy for best children’s album of the year. The album in question, “Rise Shine #Woke,” is an invigorating departure from the saccharine pop vibes of the “Kidz Bop” genre. The thoughtful and rhythmic hip-hop album has an intergenerational appeal, with tracks that discuss themes like racism, diversity and kindness.
