The follow-up to Boston's mega-hit first album, Boston, Don't Look Back took two long years to complete, and it's hard to figure out why because it's almost exactly the same as their debut. The guitars still sound like they are being fed through computers and stacked into great walls of sound by robots, lead singer Brad Delp still sounds like he is ripping his throat out, and the harmony vocals still sound like a choir of androids warbling angelically. Most importantly, the songs are overflowing with hooks, there are plenty of riffs to air guitar to, and the songs stick in your head like dirt on a dog. The main difference lies in the semi-melancholy tone of the record. Boston was a nonstop party of a record but one look at the song titles lets you know that Don't Look Back is a little different: "A Man I'll Never Be," "Used to Bad News," "Don't Be Afraid." These songs reveal a reflective side that was nowhere to be found on Boston. Not to say the record doesn't rock because it does mightily. "Don't Look Back" has a killer riff that's very similar to the timeless riff in "More Than a Feeling," "Party" is a storming rocker much like "Smokin'" and "It's Easy" is mellow 70's AOR at its absolute best. Don't Look Back is basically Boston, Pt. 2, but don't let that put you off because even though the band was treading water they were treading it like Esther Williams. This record is better than 96.7% of the AOR records released in the 1970s, combine it with Boston and you are looking at two tickets to AOR paradise.
