O! The Joy, O Lucky Man!, The Plastic Constellations, and The Reptilian

Band O! The Joy is from Sacramento. I completely enjoyed their album Zen Mode, which came out nearly a year ago. This is definitely a band I am looking forward to hearing more from. Songs and a little info are here.
O Lucky Man! is also from California. They create a lot of sound with just a two member band. Their website simply explains of a new record, but I don't know how long that has been there.
The Plastic Constellations had their "last show" on April 19, 2008. The band is from Minneapolis and have four albums from 2002-2008. I recommend 2004's Mazatlan as a starting point.

The Reptilian have released two EP's so far. I am still working on hearing one, but Boys' Life was released March 3rd, 2009. It is pretty fantastic in my opinion. Both EP's are available on iTunes.
