“Do you feel like any of this is wrong? Do any of you feel like any of this is wrong? Coz I feel like some of this is wrong,” Australian musician and activist Xavier Rudd declares on “Comfortable in My Skin,” one of thirteen eco-friendly tracks on his seventh studio album, Spirit Bird (SideOneDummy, June 2012). A one-man band who fights for the environment, indigenous cultures, animal rights, and other causes, Rudd again plays a multitude of instruments on the new record, including numerous guitars, keyboards, harmonica, drums, a stomp box, and the yidaki, (didgeridoo). In addition, several songs feature bird and whale samples; one of Rudd’s current causes, and whose call can be heard on Spirit Bird, is the endangered black cockatoo. Rudd recently participated in an online auction sponsored by the Kaarakin Black Cockatoo Rehabilitation Centre, where he’s visited. He donated a specially commissioned, signed Tjukurtjarra Didgeridoo on which he has written, “One love / One mob / For country / Arms up / Thank you, Kaarakin!” Rudd’s world music sound mixes elements of folk, pop, dance, and reggae with African and aboriginal rhythms that often border on New Age before picking up speed, especially on the epic, mostly instrumental ten-minute “Full Circle.” The album ends with Rudd pleading, “Please patience please patience please / I’m creating a dream.” You can join Rudd’s ever-growing movement on December 3, when he plays Irving Plaza in a show rescheduled from October 28, which was postponed because of Hurricane Sandy; Chris Berry opens up.
