I attended concerts by John Cale on Friday and Saturday, so those would be the last two.
The Friday concert was all Velvet Underground (mostly the Nico album) and the arrangements were very good for the most part. Cale and his ensemble delivered blistering renditions of Waiting for the Man and Heroin and a rollicking Sister Ray to end the show. Other performances weren't so good. Many of the assisting musicians - with names like Kurt Vile, Animal Collective, MGMT, Thee Oh Sees and Connan Mockasin - were clearly more schtick than substance. The women who sang the Nico parts were simply dreadful. The worst was either off-key or audibly inhaling deeply after every line.
The Saturday performance, which included many of the same assisting musicians, was all John Cale compositions. The arrangements of his old stuff were dull and lifeless (mostly plagued by mere recitations of lyrics with droning accompaniment) and his new songs were just awful. The worst was titled What Do Pretty People Say? and the lyrics were the line "what do pretty people say . . . hey, hey" repeated way too many times than was necessary (once would have been quite enough). Another included the line "ding, dong the witch is dead" (as a stand-alone concept, apparently). For anyone other than Cale, I would have felt angry and inclined to ask for my money back. But instead I just felt greatly disappointed and embarrassed for him.
