It's not uncommon for young bands to cram a bit too much into every song they write, in an effort to pay homage to all the artists that have influenced them. Feed Me Jack's sound might warrant descriptors like "scatterbrained" or "over the top," but not in a negative way. If anything, theirs is a gleeful and infectious insanity. The UC Santa Cruz act's hairpin turns in style and abrupt shifts in tempo are like a good rollercoaster ride—whipping the listener around just enough without ever becoming disorienting. When Glenn Carson, Sven Gamsky, Robert Ross and Jake Thornton jump from Tera Melos-esque math-rock, to jazz-metal explosions, to straight-up jazz and, finally, to bouncy pop or light ska upstrokes—as they do on their debut album, Chumpfrey—it all somehow makes sense.
