That was evident on Tuesday night at Barclays Center in Brooklyn, where Parker was in the middle of a sold-out, four-show run that found him helming a six-man band and playing to audiences of about 15,000. The tour is in support of Tame Impala’s fifth album, “Deadbeat,” released earlier this month, on which Parker flirts with the ego-obliterating escapism of dance music (song titles include “Oblivion,” “Piece of Heaven” and “Ethereal Connection”) but ultimately retreats into the familiar comfort of dour self-loathing (song titles also include “Obsolete,” “Loser” and “My Old Ways”).
