Instrumental prog/math rock band Challenger Deep released an awesome song earlier this month “Immersive” on us and it really, really shreds.  They also released a music video in relation with the song, which you may want to check out especially if you have a sense of humor.  The guitar work is Aaron Marshall/Intervals influenced, may I add.  It’s melodic and clean, with sweet fills between the different progressions.  The rhythm is really, really stellar too.  The rhythm section in this band really stands out in a positive light.  If you’re into that style of instrumental music I suggest you listen to the Challenger Deep guys.  I hope you dig the track and pay attention to this band!
