Considering he was such a huge star and cultural icon, it’s surprising that Prince’s eventful life and sad death has yet spawned so few ‘kiss and tell’ memoirs.

Let’s hope it stays that way. But while his long-time musical partner and one-time fiancée Sheila E certainly doesn’t shy away from sharing her memories of him in her fine autobiography ‘The Beat Of My Own Drum’ (co-written with Wendy Holden), those recollections form only a small part of a very rich, diverse collection of portraits.

After all, Sheila has played percussion and/or drums with some of the all-time greats: Carlos Santana, Herbie Hancock, Marvin Gaye, George Duke, Lionel Richie, Tito Puente, Diana Ross and Billy Cobham, not forgetting her father Pete Escovedo.

But while there are plenty of tasty music biz anecdotes, the book also provides a fascinating portrait of growing up in a mixed-race family (her mother is African-American and father Mexican) in a less-than-salubrious section of Oakland, California.

Sheila paints a rich picture of a seemingly happy childhood based around music, dancing, sports (she is apparently a pretty useful football player), charity and community, with shared cultural references such as The Carpenters (Sheila was hugely inspired by seeing Karen on the TV), Sly and the Family Stone and The Jackson 5, though there also some racial tensions around too.

But then the book goes in a completely different, unexpectedly harrowing direction when she chronicles the sexual abuse suffered as a young girl at the hands of several cousins. The section rivals James Rhodes’ recent book ‘Instrumental’ in its shocking candour.

Thankfully, if anything, the abuse drives her ambition rather than beats her down, though she admits to seeing it as a dark secret that clouds the rest of her life.

There are fascinating anecdotes about travelling to Colombia at the age of just 15 to play percussion with the Latin/fusion supergroup Azteca. Cobham, Duke and Gaye are mainly described in glowing terms, almost as father figures, and she is unexpectedly candid about her romantic and musical infatuations with Santana. There’s also a hilariously mismanaged backstage ‘meeting’ with Diana Ross.

But it’s easy to forget just how unique Sheila’s talent was in the 1980s when she made it as a ‘pop star’. We had never seen a percussionist/singer/dancer triple-threat before, as she herself points out, and Latin celebrities were very rare.

This pop period is grippingly covered in the book, with tales of disastrous video shoots, crazy tour schedules and much celebrity hobnobbing. Escovedo also very nicely juggles the spicy anecdotes with some genuine, intelligent advice for the modern musician, and just enough technical stuff about playing drums and percussion too.

Sheila also discusses her project Elevate Hope Foundation which focuses on music therapy for victims of child abuse, a noble and important program which continues to go from strength to strength.

So if the last quarter of ‘The Beat Of My Drum’ reads more like a self-help book than a famous musician’s autobiography, we can surely cut her some slack. Highly recommended.
