In psychology, the term \u201cdialectics\u201d has to do with holding two contradictory ideas at once. The concept helps<\/a> better explain the complexities of life when there\u2019s truth in two opposing views.<\/p>\n As New Orleans indie rock band Mars & Other Planets<\/a> began to go through some significant changes in the last few years, dialectics was an idea that Marissa Douglas<\/a> returned to often. Douglas had built her musical identity around guitar and her vocals, but after chronic pain made playing guitar more difficult, she decided to focus on the keyboard. That led to new instruments, new sounds and new ways of doing things as Mars & Other Planets<\/p>\n So \u201cDialectics\u201d ended up being an appropriate title for the band\u2019s eclectic, new album<\/a>.<\/p>\n \u201cTo me, the ultimate kind of dialectics in this was on the one hand, me not being able to play guitar as a result of chronic pain is so disastrous, and also it gave us this opportunity to create a new sound and feeling,\u201d Douglas says.<\/p>\n Mars & Other Planets released \u201cDialectics\u201d in early February, and the trio \u2014 Douglas, baritone guitarist Chris Billiot and drummer Lex Condes \u2014\u202fplay an album release show on Friday, Feb. 27<\/a>, at Carrollton Station. Keaton Schiller and Lisbon Girls also are on the bill.<\/p>\n
