(MACKENZIE - 2010) GUITAR HERO INTERVIEW: NOEL GALLAGHER By Marcel Anders Oasis lead guitarist Noel Gallagher has been described as the elder statesman of British rock. Yet this is a description that he rejects, pointing out that, at the age of 41, he is still a young man, when compared with the likes of Mick Jagger, Keith Richards and even Paul Weller. Gallagher, who has often been in conflict with the Oasis lead singer, his younger brother Liam, recently met with the press in order to promote the bands latest album, Dig Into Your Soul. As he explained, some of its songs were inspired by his memories of LSD trips as a teenager in Manchester: Noel Gallagher: What do you write about when youre 41? I dont know. You know, __( I )__famous? Nobody wants to hear about that. __( II )__ in a band? That was kind of what Definitely Maybe was about. Women? Too boring, you know. Money? Nobody wants to hear about that. Politics? __( III )__, you know. Save the planet? __( IV )__. You know, I dont know. So, the most __( V )__ thing is like, well, I remember when I was 16 and, you know, __( VI )__ acid, it was like, Yeah, theres stories to be told there, I think. BACK ON TRACK Many critics say that Oasis are back on track with this album, but Gallagher has his reservations: Noel Gallagher: For me personally, I dont know what anybody else in the band thinks, but when I sit down and write a song I dont think: Well, is this as good as what Ive done? I just write them, you know, and record them and other people decide. So, if other people decided that we were back, you know, after Dont Believe The Truth, then great, do you know what I mean? But I its not something that I would ever I wouldnt enter into a debate about it. How can I, you know? I dont Im not a professional songwriter, do you know what I mean? I kind of its what Ive been writing songs for as long as I can remember, you know, for fun, its just so now lots of people buy them, but if nobody bought the records tomorrow, I still wouldnt stop writing songs, but Id write songs just to play to my mates. Its kind of what I do. ABBEY ROAD Dig Out Your Soul was recorded at Londons famous Abbey Road studios, whose previous occupants have included The Beatles and Pink Floyd. Rumour has it that Oasis had previously been banned from the studios on account of their unruly behaviour: Noel Gallagher: We had to pay the money upfront and promise to be on our best behaviour. We had to pay the money upfront, and so they said, If if you have to leave, then youre gonna lose the deposit. Well, its different now, you know, when we were in there in 97, everybody was in their 20s and whacked out on drugs all the time, so its different now. Everybodys got kids, you know. Everybodys a little bit more a little bit less mental, you know, but we still have a good time, though. We made a great record, thats the main thing about it, you know, and its good for Abbey Road, that somebodys finally made a great record there!

(MACKENZIE - 2010) Adventures in Sub-Consciousness By Sarah Modlock ___(I)___ you fancy a little underwater exploration without the hassle of learning to scuba dive, youll love the sub-scooter. Its a battery-powered moped that propels you through water at a depth of 10 ft. (3 m), ___(II)___ compresses air is pumped into a tiny glass cockpit from a boat on the surface - the resulting air pressure keeping water out of the wood. Pelagic treasures can be seen without even get you hair wet. The sub-scooters downside is that it is only found in Mauritius. But the upside is that you have another excuse - ___(III)___ the deep-sea fishing, the beaches and the tranquility - to visit this beautiful island nation in the Indian Ocean. Part of the vessels charm is that it offers an underwater encounter with no need for heavy oxygen cylinders or uncorfortable mouthpieces and masks. ___(IV)___, the motor is virtually soundless, leaving sea creatures undisturbed and preserving a sense of the exotic. It wont take you long to get a feel for the acceleration and steering, and you wont need brakes: the coral is a low-lying, and theres nothing to bump into apart from other sub-scooters (__(V)___ theres little chance of that with scuba-diving guides pointing the way). Sure, the sub-scooter is too sedade for James Bond and probably rahter restrictive for experiences divers, but its still a thrilling experience for visiting water babies. A two-hour excursion, including 30 minutes on a sub-scooter, costs about $160 for two people. Visit www.blue-safari.com for details.
