The new track "High Horse" is definitely the least upbeat tempo as the band that's most known to me and countless others for their propensity for tight-knit, intricate jams more or less takes a break from that to get a bit of emotional catharsis. The result is a beautiful and touching tribute to a lost loved one that sees the band turning enough of a new leaf to keep things interesting without flipping the script entirely. It's the kind of change that'll no doubt help Rainer to really feel like a full, mature work.
