The Boston music scene has always been an incubator for young jambands, and the city’s latest crop includes improv-rock outfit Strange Machines. Fostered for the last six years by their “Strange fam” following, the band’s first full-length Voice of Color is yet another step in the right direction for the fourpiece, who have recently made strides opening for acts like Twiddle and Turkuaz. Founding member and lead guitarist Mike MacDonald is the real all-star on this record, laying down an impressive solo at the end of the nearly 10-minute “Golden Rule.” His virtuosity is worth a second (and third) listen. However, that doesn’t mean that Voice of Color is without its shortcomings. At times, the vocals are a little too front-facing in the mix and, clocking in at 75 minutes, it could have been tightened up to amplify standouts like the title track, “The In-Between” and “Squid.” With multiple songs surpassing the nine-minute mark, it’s clear that these guys love their extended compositions, and they definitely flourish rather than flounder under all that sheet music. Genres vary from reggae to funk to straight-up rock, but the free-form moments are always there, ready to take off. Honorable mention goes to jack-of-all trades keyboardist Christian Perron, who somehow fits in jamtronica synths and Page McConnell-esque piano solos within the same LP. All things considered, in a city that births new bands every day, Strange Machines have carved out a lane for themselves in Beantown and beyond.
