"I don't understand why some people can't seem to get into DCT's earlier work, but I think maybe they're just not listening hard enough."
Entirely possible. I only had 2 days to rip the 10 CDs, so I was only listening to each track for a minute or less before deciding to keep it or not (to keep the rental exercise semi-honest I was limiting myself to 650MB of 320kbit MP3s, not just ripping all of it to CDDA). Under these conditions the first album was largely "meh".
But "Kanashii Kiss" is awesome in the WL '95 video, as is the "Kare-wa Tomodachi" medley segment in that concert. Both songs sound a lot better in the video than the 44sec samples at
http://dctgarden.com/disco/album.html for sure.
But I think it's mostly a theme thing. Miwa's earlier songs mine a similar vein, but she branches into more accessible (to me) stuff in the late 90s. Here's my "must-have" DCT songs:
1. Ai-suru Kokoro (1997)
2. Asa-ga Mata Kuru (1999)
3. SNOW DANCE (1999)
4. PEACE! (1997)
5. ROMANCE (1995)
6. LOVETIDE (1993)
7. Ureshii! Tanoshii! Daisuki! (1989)
Basically I can rank these wrt favorability by reverse chronological order, the newer the single, the more I like it (sadly, the singles of this decade haven't done much for me).
I think it's the first 4 albums were formative (with the lyrics chasing the sound), the middle 4 were solid, DCT at their peak, a good balance between lyrics and sound, and the five albums since LOVE UNLIMITED have been post-peak with stronger lyrics and musical ideas but less balance and coherance than the peak-era albums.
