Thao Nguyen has been busy since her last album, Know Better Learn Faster, came out in 2009. The band moved to San Francisco while Nguyen explored recording with other artists, even making an album with Mirah.

When Kenneth Pattengale and Joey Ryan ditched their solo careers to form The Milk Carton Kids, they discovered that they had a lot to teach each other. They also had a plan: to give their music away in order to find their audience. It worked remarkably well. Now, their third album, The Ash & Clay, is out on a regular label — no freebies this time around — and they're playing to packed houses across the U.S. and Europe.

You could hear it in their first singles in 2011: Sisters Jessica and Jennifer Clavin and their band Bleached are onto something. Now comes their debut full-length, Ride Your Heart, and it fills in the story: Beachy harmonies combine with punk attitude to take what you loved about Best Coast to a grittier place. It's fun and it's heartfelt — what could be better?

While on tour with his band Guster, Adam Gardner noticed that a lot of energy was being consumed, particularly in getting bands and fans together for a show. His wife, an ecologist, had been nudging him at home to become more green, and he'd started to wonder what could be done about the environmental impact of life on the road.

The last few years have found Mark Oliver Everett of Eels doing more than a bit of summing up. That includes an autobiography, Things the Grandchildren Should Know, as well as an anthology of the band's past work — all while putting out an inter-related trilogy of new studio albums.
