The songs that make up “Package Pt. 2” from Gustaf are a logical continuation of the powerful debut LP by the NYC five-piece, with more loud, in-your-face punk songs but also some surprising detours into experimental grooves. Gustaf’s singer and lyricist Lydia Gammill shed light on this new LP, WNXP’s Record of the Week, in advance of their U.S. tour, which stops in Nashville May 17 for a WNXP Presents show at DRKMTTR.
