Patrick Paige II has been imbuing The Internet’s music with inimitable bass lines that are both circular and serpentine, capable of blending into the mix on tracks like “Girl” or stealing the show on “Special Affair.” Along the way, the band’s secret weapon has been quietly carving out a solo career for himself, dropping records like “(Tears For) Souls I Never Knew” and “You Ain’t Missing Much” that prove his skill as a songwriter and, in the case of the latter, his considerable gifts as a rapper and lyricist.
