I'll add MGMT to the mix. Their first album Oracular Spectacular gave us a few well-known pop hits, but their next albums Congratulations and Little Dark Age veered deep into psych rock and totally alienated the pop fans. The new albums are totally unsuited for casual listening and are probably best enjoyed with some scheduled substances.
I find it so interesting how their self titled album has just been zapped from everyone's minds. The other day somebody said to me that every single album they've made has been fantastic, so I brought up the self titled and they'd never heard of it! Same with you I assume.
I think most people who are really into the band prefer the B side of OS and consider Congratulations their magnum opus.
