Here is a short artist description based on the information:

With a career spanning over 35 years, he has released numerous solo albums and collaborated on more than 150 albums with other artists, showcasing his versatility and talent.

Translation to English (UK) is not necessary as the text is already in English, but I can provide the same text with some minor adjustments to conform to UK English spelling and vocabulary:

Note: Since the translation to English (UK) is not significantly different from the original text, the above text remains largely the same. However, if you'd like, I can make some minor adjustments, such as changing "renowned" to "celebrated" or using UK-specific vocabulary, but it would not alter the overall meaning or content of the text.
