Last night the Bluebird was filled with the purest rock sounds around and from the upstairs balcony I saw a lot of classically stiff bodies with bobbing heads.  It was however, a little too much of a roller coaster for my taste.  I definitely enjoyed the show, but the long, resonant, and softer build-ups were too long.  I caught myself standing like a flamingo just so I wouldn't fall over as I was being lulled by the music.  The parts of the songs where the band hit hard were awesome, and I'll admit that the build-ups helped the harder parts to be more shocking, catching a first time listener off guard and increasing the sense of the epic.  The highlights of the show were watching the drummer, who was apparently a guest drummer, and hearing the few tracks with vocals.  In my preliminary reading I found out that the vocal tracks are something new for this band and most likely an attempt to branch out from their previous work.  I have the impression hardcore fans are not quite fans of the tracks with vocals, but since this was my first time listening, the vocals drew me in.  Mogwai is a great rock band and I was lucky to be in the crowd last night, but their show is better suited for those who know their music.  Instrumental up and downs are magnified the more one listens to a song and I need to give Mogwai a few (a lot) more listens before their patterns become recognized and loved.
