Trick Pony had the two-guys/one-girl, good-timin’ trio market cornered before disbanding in 2008. Trailer Choir is ready to take up the mantle with an album that revels in eternal summer themes of parties, dancing (“Girls Love to Go Dancin’,” “Shakin’ That Tailgate”), drinking and simple love (the jovial “Rollin’ Through the Sunshine”). Luckily, all the fun doesn’t have to come with a hefty price tag. A backyard pool and tequila make for cheap de-stressers in “Homemade Mexico,” and a 99-cent card and a candy bar are appropriate tokens of love in “Wal-Mart Flowers.” While Crystal’s strong and soulful voice cools down the rough-edged lead vocal of Mark Fortney (aka “Butter”), it is hard to take this trio seriously. Artists like Brad Paisley and Trace Adkins have found success with lighthearted fare, but they smartly balance funny songs with more sober themes. This trio seems content to let its unexceptional summer ditties last all year long.
