Black Francis has offered some words on the departure of bassist Kim Shattuck, and why she had a short tenure in the Pixies. His comparison is that it's more like dating than it is a marriage. In a recent interview with Yahoo! Music, he said:
“I guess it’s a fair question, but what I would say is, just because some shows went well or a recording session went well with somebody, that doesn’t mean that now you guys are married and this is forever. It’s not really how it works when you’re a band. And it’s hard to explain to people, especially if they get emotionally attached to one person…
Which is maybe a good place to be as a band. The Pixies have the option to "date" different bassists for new releases, letting each one have a different influence on the album, and if they dig the influence, maybe they stay in the band for more than one release or tour.
Kim Shattuck was recently let go from the Pixies, at a time when she thought everything was going well. She replaced the founding bassist Kim Deal, who is currently doing other musical things like The Breeders. Paz Lenchantin is their new bassist.
Then Black Francis went into a more grinding commentary, saying that in the age of hyper-context, people don't have to explain everything that ever happens in an over-dramatic public discourse.
“Frankly, you don’t want to explain it to anybody – it’s a lot of its personal, private shit. It’s like politics and sports and people’s personal lives have all been smeared together in this modern world. It’s a very presumptuous attitude about a lot of things. [People say] ’Oh you’re shifting something in your world – we demand a statement as to why.’ I’m not the mayor, this isn’t the bus service for a town. This is a rock band. There’s been a shift in the lineup, big woop-dee-doo…as far as we’re concerned it ain’t that big of a deal.”
Then again, maybe they'll get back together with Kim Deal.
