vividblaze (Recommended by one80)
Jazz-pop band with female vocals, just the way I like'em. Very catchy riffs.
cuetracks (Recommended by one80)
Acoustic pop with some electronic bits. Quite varied - some of their songs are summery and relaxing, and a few tracks are quite experimental.
NOMOTO karia (Recommended by haikara_girl)
Shibuya-kei, influenced by bossa nova and French pops. Excellent (perhaps better than the original)
rendition of Pizzicato Five's 'Wild Strawberries'. Currently addicted to her head-bobbing at the 1:00 mark.
Jill-decoy Association (Recommended by lalasunday)
Jazz-influenced pop. Female vocals on a very bold bassline. A few 'crank-it-up' tracks mixed in with some ballads.
the band apart (Recommended by formosalovin)
Indie J-rock band, melodic, upbeat. Excellent guitarist. Can't comment more because I may or may not have lost your cd school captain-san (sorry!)
