The follow-up to Boston's mega-hit first album, Boston, Don't Look Back took two long years to complete. It is hard to figure out why it took so long because it is 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. 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 block rockin' record but one look at the song titles lets you know that Don't Look Back is a little less upbeat: "A Man I'll Never Be," "Used to Bad News," "It's Easy." 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'." 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 95 percent of the AOR records released in the 1970s.
