  We present INTEGRAL spectral analysis in the orbital/superorbital phase space
of LS I +61 303. A hard X-ray spectrum with no cutoff is observed at all
orbital/superorbital phases. The hard X-ray index is found to be uncorrelated
with the radio index (non-simultaneously) measured at the same orbital and
superorbital phases. In particular, the absence of an X-ray spectrum softening
during the periods of negative radio index does not favor a simple
interpretation of the radio index variations in terms of changes of state in a
microquasar. We uncover hints for the superorbital variability in the hard
X-ray flux, in phase with the superorbital modulation in soft X-rays. An
orbital phase drift of radio peak flux and index along the superorbital period
is observed in the radio data. We explore its influence on a previously
reported double peak structure of radio orbital lightcurve, posing it as a
plausible explanation.
