Language grounds the climb of music. Without the baggage of lyrics, songs increase altitude, with more legroom to boot. The fifth annual Austin Instrumental Music Fest promises not only height but weightlessness through spacious instrumental arrangements and spacey sound design. Heavy Stars’ looped vibraphone whispers, Brainwavve’s electronic meditations, and Ramparts’ featherlight math jazz-rock highlight two-dozen acts on three stages.
