Three years ago, Paul McCartney was one of the most outspoken of the disgruntled acts at EMI, the record label that had been his home since the earliest days of the Beatles.

He complained in an interview with The Times of London that he and other artists at the label, which had recently been bought by the British private equity firm Terra Firma, were treated as “part of the furniture.” He signed a deal with the Concord Music Group, an independent label in California, for his new releases.

Now, in another blow to EMI, Mr. McCartney has pulled his full catalog of post-Beatles albums, signing a new deal with Concord for worldwide distribution of the catalog, Concord said Tuesday.

EMI declined to comment on the news, which was first reported by The Wall Street Journal.

Since Terra Firma bought EMI in 2007, the label has suffered a number of prominent, and sometimes acrimonious, artist defections. The loss of the McCartney catalog may be of great symbolic significance, but his recent sales have been minimal. Last year, all of Mr. McCartney’s solo albums on EMI — including his work with Wings — sold about 95,000 copies, according to Nielsen SoundScan.
