According to various BBS,
Akina mentioned at her dinner show 2006 that :
1. 「チャイナタウン」「リバーサイドホテル」「いい日旅立ち」 will be new recordings that are included for the release.
2. The cover for 歌姫ベスト is said to be of 豹柄の着物 ( Lepoard skin theme) and hairstlye was said to be "as if hair was burned by fire????" (implying an explosive-like hairstyle?? a big perm??)
Anyway, good to look forward to all the above.
In addition, Akina is confirmed to appear on Heyx3 on 15th Jan 07 for a talkshow corner (meaning no singing… =( )
