Since my daughter started her high school music program years ago, we've made regular visits here…read morefor various music needs, from instruments, to accessories, and printed music.
They have the most impressive selection of instruments, similar to the flagship Long & McQuade. As a suburbanite driver, I have to say that I'd rather travel to Cosmo, where there's all kinds of plentiful parking, not to mention an in-house cafe! It's a Terminal 3 Roasters chain location (plenty of Yelp reviews on that if it is of interest.) They proudly display their top retailer award for instruments, which I regrettably can't remember the name of specifically. In any event, it's no surprise. Room after room and floor above floor are filled with display models, and if it's not on display, they can order it for you.
While they do carry a full range of beginner to high end instruments, they also have some used offerings.
Perhaps not surprisingly, they offer music lessons as well. The rooms are clean, with a large waiting area stocked with toys and activities for those siblings stuck waiting. They even have a fascinating museum of famous musicians complete with plaster hand prints, signatures, and biographies to accompany their photos.
When it comes to their printed music selection and accessories, it's good, but not extensive. They cater more to the private individual as opposed to professionals, and don't always keep up with gaps in stock. In terms of accessories, it's pretty much the same - you may or may not find what you need in stock.
They also carry quite a wide range of non-instrument related merchandise like t-shirts, vinyl records, trinkets, etc. for music lovers, so even if you don't play, you can find neat stuff for yourself, or music lovers on your gift list.
I would definitely recommend checking this place out at least once, and especially if you're researching for a big instrument investment. We've been coming for years, and will continue.
