Using sox as an alternative to mp3wrap to losslessly concat a dir full of mp3s?

I wanted to combine all mp3 files into one in each directory using
Ubuntu command line.

I started using a thing called MP3Wrap
(https://sourceforge.net/projects/mp3wrap/)

It was as simple as

mp3wrap -v "wrapped.mp3" ./*.mp3

except it turns out to horribly break id3 tags, doesn't recognise vbr
properly etc.

Is there are way of losslessly concatenating mp3 files with sox, or is
it a job for another tool?

I know about "--combine concatenate", but that seems to re-compress the files.

(The ability to unwrap the combined mp3 into individual files isn't a
requirement, but it would be a nice thing if possible!)

Thanks
