Leonard Link reports Naxos will issue a series of recordings with all of the songs of Charles Ives. I have days where I think this collection of songs represents the greatest achievement of American classical music. At a mininum, I'll take the songs to the proverbial desert island.
Leonard does chide Naxos for ordering the songs by title rather than in a more satisfying manner. This will mean ripping to MP3 and constructing playlists, I suppose.
Also, it appears the texts generally won't be available. Fully appreciating the music without them is difficult. I solved that problem in the past by buying the music to 114 songs; couldn't afford the $250 for the 129 songs though.
By the way, it looks like lala has free streaming for about 15 recordings of Ives songs including Dora Ohrenstein singing The Collection.
