For anyone with successful siblings, the key is to break out and be your own butterfly or whatever. This is exactly what Zechs Marquise, started by Marfred and Marcel Rodriguez-Lopez, the brothers of Mars Volta founder Omar Rodriguez-Lopez, have done. They’re not sitting in their parents’ living room wishing Omar had never been born. And they’re not riding on the coattails of Mars Volta’s success, either (well, maybe a little). They’re creating distinct songs that mix funk, psychedelic and rock, so get off your ass, stop griping at your parents that they should have had you first, and go get a job that showcases your own unique talents, for Christsakes. Zechs Marquise play three shows at the Gramercy Theater March 25, 26, and 27, 8 p.m., $18, all-ages. zechsmarquise.com.
