Question about RØDE smartLav+ incl. SC3 adapter

You can of course use it to record a rock concert, a violin concert or even the floor.... :-)
And now seriously: Of course you can record a rock concert, the question is only what quality you expect from the recording in the end. Microphones today are available in many different types, specifications and designs, which in the end is always reflected in the quality of the recording. This microphone has the characteristic of recording speech at a certain proximity in the highest quality. A lot of bass, 100db and a certain distance to the concert speakers are certainly not ideal for this mic. However, as mentioned, recording is certainly possible. But it might also be forbidden... ;-)
