They're not from late '60s London, Mmoss are actually from modern-day New Hampshire. Not that you'd notice after a listen to the band's album, simply titled i.
It's rooted in that late 60s era, think UFO club, think Notting Hill squats, think acid folk, early Krautrock, think…well, you get the idea.
Anyway, rather than me babbling, let me tell you this…you cans stream the album online for free and if you want to buy the download, you can for $4.20. Alternatively, the band, knowing its audience, has also run off 300 copies on 150g vinyl for $14. They even do a cassette. Why? Who knows. Anyway, check it out, it's pretty decent.
