I don't have any of these.... how many are there... which are the best ones?
There are currently nine, with new ones releasing each month. The majority of them are re-releases of CDs that were released by YtseJam Records in the 2000s, so if you're a long-time fan, you might already have some of them.
Three of the current releases, and the new one coming out next month, are demos. These are:
- Train of Thought Instrumental Demos
- The Majesty Demos
- Awake Demos
- Falling Into Infinity Demos (upcoming)
The other six releases are live performances:
- Images and Words - Live in Japan 2017
- A Dramatic Tour of Events - Select Board Mixes
- Master of Puppets - Live in Barcelona 2002 (a cover of the Metallica album)
- When Dream and Day Reunite
- Live in NYC 1993
- ...And Beyond - Live in Japan 2017
These releases offer different things that might be of greater or less interest to you depending on what you like and what you're interested in. Here are the ones that I think are likely to be of most general interest to Dream Theater fans, with a little bit of why you might find them interesting.
- Live in NYC is a full show from the Images and Words tour. The band is really on the top of their game, with a ton of great performances. Plus, you get three hard-to-find songs: To Live Forever, Eve and the 1993 version of A Change of Seasons.
- The Falling Into Infinity Demos is the most interesting set of demos the band has released. This is because they include five songs that did not make the album, only one of which (Raise the Knife) is easy to find elsewhere, plus alternate versions of a lot of the songs that did make the album. They also include the Metropolis Part 2 demo, which is the earliest version of what became Scenes from a Memory
- When Dream and Day Reunite is of special interest to people who aren't fans of Charlie Dominici's voice on the first album. This is a live performance of the full album with James singing. It also includes To Live Forever and Metropolis with Charlie and Derek Sherinian as guests.
- The Majesty Demos is interesting if you're curious about the early history of the band, because you get songs that they recorded well before the first album. However, I don't think these songs are all that great on their own terms.
- A Dramatic Tour of Events is a great 2CD selection of live songs, including some what don't have any other live version or are pretty rare: The Count of Tuscany, The Great Debate, To Live Forever. But don't be deceived by the title: Nothing from the ADTOE album is on here. This covers all the songs played on that tour that were not on Live at Luna Park. Also, this was a free release for fans around Christmas 2013, so check to make sure that you don't already have it under the name "Happy Holidays 2013."
- ...And Beyond is another quality live release that includes some songs that don't have a live release elsewhere: The Bigger Picture, Hell's Kitchen, The Gift of Music, Our New World. Unlike Dramatic Tour of Events, this is a single CD that all comes from one show. This is actually the first half of the 2017 Japan concert. Images and Words - Live in Japan is most of the second half. Personally, I think ...And Beyond is better, because James's performance on the older songs from IAW is a bit spotty, while he sounds pretty good on the newer ones on ...And Beyond.
