Via Weathervane Music’s Twitter: Mariner Nine—the band Weathervane Music co-founder and local producer/engineer extraordinaire Brian McTear originally formed with David Boyd, Jason Knight, and Matt Neal (as Mother’s Garden) back in 1990—would have officially turned 20 years old today. (The band’s first show was on January 12, 1991, at The Hill School in southeastern PA—which McTear, Boyd, and Knight all attended.) To celebrate the occasion, the four original members of the band (along with “manager” and honorary member Tyler Harold) returned to the studio last year to record a few new tracks. The three-song EP, appropriated titled “Twenty,” was recorded at Miner Street Recordings in September 2010 over Labor Day weekend. You can listen to the first track, “AZ-yoosa Plane” (featuring lyrics and vocals by McTear) below; all three songs are available for free download via Mariner Nine’s Bandcamp page. You can also check out a handful of older songs (and an extremely detailed bio) at the band’s MySpace page.
