Shudder to Think were on to their 2nd album by the time Into Another formed. I doubt the similarity was coincidental given how much Rev Recs bands took their cues from DC. They were obviously listening closely Jane's Addiction and Supertouch at the same time too.
i really doubt they ripped off shudder to think given that both bands started around the same time. STT is definitely the closest-sounding band to into another, but i think that's probably just a coincidence.
