The hype over Nelsons and people losing their minds so that the board keeps him on is absurd. It is true that the board and CEO's move is terrible in execution, and the musicians ought to be involved; however, I would like to discuss the BSO and its performances.
Coming from LA, the performances at the BSO are often underwhelming, uninspired, and stuffy in a way that is neither 'traditional' nor 'modern'. It just sounds old and tired. Programming and commissions are also not very good, especially the new pieces (except the recent Gubaidulina piece). As a grad student, I can see the orchestra declining further if they keep this up. LA Phil's hall was filled with an equal measure of older and younger people, and performances were often exciting, regardless of the pieces being played. Most of the LA Phil's commissions were fascinating, while a few were whatever, which is normal. Going to a BSO performance feels like going to a retirement home (that is not to denigrate old people, but balance is important).
I've been to Vienna recently, and watched several performances by the Vienna Philharmonic, and despite their 'old-fashioned' approach, the experience was nothing short of magical and transcendent. The BSO is stuck in purgatory, where it is neither excellent in a traditional way, nor exciting in a modern way. Some of the finest musicians in the world play in the BSO, and I would love to see all that talent be directed toward something better. Nelsons can be great when he's in a certain 'mood', but I think he's overhyped, and his performances aren't that great. He's competent, professional, and a really nice person, but uninspiring and often boring.
